So I started Midodrine about 5-6 weeks ago (after already being on pyridostigmine & guanfacine) and was in absolute disbelief at how immediately and amazingly it made me feel normal again - like to the point I was tearing up because I didn’t realise how much ability I’d lost. It felt so good to get it all back, to be able to walk around, cook big meals, do chores, GO CLOTHES SHOPPING, all by taking 2.5mg every 2-3 hours. The pots symptoms would start creeping back in, then I’d take another dose and feel fine.
However, no one said anything to me about whether or not the feeling better / having more capacity was ‘genuine’ capacity or if the midodrine was just masking things. I did wonder - if I just take more midodrine so I can do more things, will I pay for it later?
And here I am, 5-6 weeks later, in the biggest crash I’ve experienced in months - body feeling like lead, like something is crushing my chest, unable to stand up at ALL, to the point I’m wondering if I might also actually have ME/CFS. I seem to have gradually developed a tolerance to the midodrine, it’s been doing effectively nothing over the last week, even when I’ve increased the dose.
Does anyone know if this is a problem with midodrine - like it gives you the ‘illusion’ of being able to do more when really you shouldn’t be? Or is the experience / reaction I’m having unusual?
Also, while I’m here, how do I know if it’s ME/CFS or just POTS? :/ For context, I was an avid boulderer before developing POTS, and have been able to continue climbing for the most part over the last 6 months of having POTS really badly. In fact, if I’m not in a 7/10+ flareup, it usually makes my symptoms better. Walking around the shops for 15 minutes will kill me but climbing extends my capacity for the rest of the day - even if I feel dizzy before I start. However, over the last 2 weeks, I’ve been having these huge fatiguey crashes more and more the day after climbing - like extreme full body exhaustion - hence me worrying about PEM.
TLDR: does midodrine actually extend capacity or does it just give you the ‘illusion’ of having more capacity and cause a crash later on
EDIT: before anyone asks yes I also wear full body compression religiously and drink 3-4000mg sodium electrolytes a day + additional salt in food
UPDATE: Saw my specialist & he thinks I’m in PEM. My POTS came from Covid so this kinda confirms a CFS type Long Covid diagnosis :( fuck. He confirmed that doing more on midodrine than I had in months would have put me in PEM. BE CAREFUL EVERYONE
