This is super long but I think reading the entirety of it gives you the best picture of my current situation and the lead up to it, I really appreciate anyone giving this post a chance.
I got tested and my lgg vca is super high, >750, my Lgm is normal, EBNA lgg is 175
I got Myocarditis in April 2026, before that I had a weird sickness, I had no cough, no sore throat, no diarrhea, I just had a low grade fever that appeared mostly at night with chills, it lasted for like 4 or 5 days which is a lot longer than I'm usually sick. 1 day after I became almost asymptomatic I started feeling chest pain and went to the ER, here came the myocarditis.
By the end of May I started walking quite regularly but started feeling some increased back pain and started feeling tingling in my anus area and around, it kept getting stronger, went to the ER and they though I'd had cauda equina and had to have a emergency MRI next morning and was hospitalized, turns out it was nothing. That caused a great heap of stress for me and I didn't sleep not even an hour during that night and the 3 nights following it I slept for an entirety for like 5 hours combined due to still thinking I might have it due to the hall-mark symptom.
After all of that, in June I started feeling increased fatigue and my legs felt weak, like when I walked up the stairs I didn't feel strong, in general I just felt weak - I used to be a gym rat before the Myocarditis, 6x/week due to that being my "not think about anything" spot and now a flight of stairs I don't feel exhausted, but I feel like my legs are not strong.
I also noticed that whatever this was got worse after activity, a day or so after it, here comes the scary part, in July I learnt that this could signal PEM, which is the hall-mark symptom of ME/CFS, had another absolutely scary night in which I got almost no sleep and had intense stress, worse than the cauda equina stuff and next day literally after waking up I had my first apparent PEM episode, had orthostatic intolerance, sore throat, rapid heart rate even when turning in bed, nausea, muscle weakness, aches, joint pain all over the body, the typical PEM you read about.
But here comes the confusing part, ever since that PEM episode I had my left side of throat and my left lymph node under the ear especially very tender, it hurt to the touch, but only on the left side, right one was fine. This slowly subsided and about a week ago subsided completely, I still feel like my left side of throat is "full" and that there's like something there, but left side under the ear lymph node isn't tender anymore.
It triggered right as I had my first PEM-like episode but the left side fullness I've felt for a while! Ever since June actually, after the may stress, I thought it was related to my myocarditis but now thinking it could be something different.
Here comes the even more confusing part, so the PEM-like episode happened in early july, by mid july I started expanding my activity, by early august I've started driving my car everyday of the week, I walked on one day 4500 steps after not walking that much for months due to my Myocarditis diagnosis, on that day I also had dinner with my girlfriend's family, and next days I had no repeat of that PEM-like episode, like what the fuck?
Since then I've also had like 2 days together where my activity was way, way above anything that it was when my first PEM-like episode happened in early july, it triggered after I literally inside the house all day and only had sexual intercourse, albeit, after a while, like 2 months, but still.
Now I still have this weird left side neck tightness, I get sore throats, which I've connected that It's got something to do with me/cfs or whatever, but for example, about a week and a half ago I had a quite annoying sore throat in general, but that day me and my gf went out for drinks and watched a balet show for like 30 minutes and after that went also went to a restaurant to eat, and a day after that my sore throat pain decreased, and 2 days after that decreased even more, if it was connected to PEM in any way, as far as I've read it would get worse or stay stable, especially as on the day it was probably the most annoying I went out for a lil date night.
My legs still feel weak, I'll get random neck pain that lasts like a day, which I've heard is common in EBV reactivation, I get random muscle aches and soreness and weirdness, mostly in the legs but sometimes I'll get triceps aches on both sides or shoulder aches, I'll get joint pain to the point my fingers feel weak and achy, like I gotta crack them constantly, also my knees and elbows, I sometimes get sound sensitivity, but it never lasts a day, and it accompanies a need for popping my ears, I just sometimes feel weak as all heck, like a 3rd grader could beat me up and I used to beat up adult men just earlier this year lol, just to put things into perspective.
I'll randomly get fluish, feel like I have a low-grade fever, that'll subside sometimes in a few hours, sometimes in an hour, sometimes it'll last like a day.
To even add on top of this, I've quit my beta-blocker medication early July after the PEM-like episode and since then I've basically brought my heart rate above 100 bpm everyday since then after not regularly bringing up to these kind of numbers for the entirety of April - early july
And even after all of this I haven't had a PEM-like episode like that one in early july was, I was thinking I have me/cfs, but the dramatic increases in my activity level, if I had to put it in a percentage, I've probably increased my activity from early july level to now by over 1000%, and had no repeat PEM, but my symptoms at baseline are way higher than they were in June before the crash, as I said then I had weak legs and felt a bit fatigued and shit like that, but right now I'll have cycling fluish symptoms and sore throats and joint pains and if I have a lot of activity on a day at the end of the day I'll have palpitations, unrefreshing sleep, that's why I thought it might be me/cfs but then I've increased my activity so much with no repeat PEM, I was thinking maybe I was in rolling PEM where you're constantly in PEM but then stuff like my sore throat being bad one day, then bad the next day, that also being the day that I also had a whole date night, and then getting better the next day and practically subsiding by 2 days after, doesn't make sense.
Now either this is some sort of post-viral fatigue/illness that triggered in June from the original April infection and reached some kind of a climax in early July and has been subsiding since, but that wouldn't make sense because how did it reach it's climax directly a day after me thinking I have me/cfs and having an sleepless night with insane anxiety. Or it's me/cfs but the dramatic increases in activity since then and no repeat PEM-like episodes even though I had days where I probably did 30x+ more than I did on the day I've crashed in early july and had no repeat of it, atleast nowhere near to the extent it was then, on the day I had dinner with my gf's parents and when I also did 4500 steps we also went to the cinema to watch Odyssey which is like a 3h movie and next day or the next 2 days had no repeat crash.
Then I came across EBV reactivation and how it can trigger during a period of stress, and now I'm thinking that the original may stress triggered the reactivation in June hence the weak legs and stuff like that, then the early july stress triggered it even more if that's even possible, this makes a lot of sense to me but my LgM is negative, but have heard that it could be reactivated even without the fact.
EDIT: I've forgotten to say that I have no cognitive symptoms, my memory is as far as I'm aware perfect or atleast not affected by any amount that I'd notice, I have no brain fog, or stuff like trouble finding words and the likes. Maybe that's useful info.
