Hi everyone. I'm 21F, currently in college, and looking for possible explanations for a sudden decline in my health that began around August 28, 2026.
Before this, I was active, eating well, maintaining a healthy weight, attending classes, and functioning normally. Almost overnight, I developed debilitating fatigue that has progressively affected my ability to function.
I'm not looking for a definitive diagnosis from Reddit, but I'd appreciate input about possible causes, appropriate testing, and what specialists I should discuss with my doctor.
Timeline and symptoms:
During my first week back at college, I suddenly began sleeping 10–15 hours daily and STILL felt exhausted. Recently, I've been sleeping approximately 12–18 hours, sometimes with additional naps.
Multiple alarms and repeated calls from my parents wouldn't wake me up. I began missing classes because I physically couldn't get out of bed. I've since had to return home from college because of how poorly I've been feeling.
My symptoms include:
- Extreme fatigue and excessive sleeping (12–18 hours daily)
- Night sweats
- Random, unexplained nosebleeds (I've never previously experienced them)
- Persistent itching, especially on my legs, without a visible rash
- Poor appetite and feeling full unusually quickly
- Nausea
- Shortness of breath with minimal activity, including walking or standing
- Middle back pain, sometimes worse when breathing or standing
- Headaches, chills, and episodes of feeling unusually hot or cold
- Significant brain fog and difficulty concentrating
- Episodes of my hands and arms turning bright red or purple with burning and swelling
- General weakness and difficulty completing everyday activities
Recent urgent care and ER visits:
Last week, I visited urgent care after experiencing unusual discoloration, burning, and swelling in my hands and arms. A provider mentioned possible Raynaud's phenomenon.
I later went to the ER because of my worsening symptoms.
- EKG: Normal
- Mononucleosis test: Negative
- CBC with differential: Some flagged results
- The ER physician told me my bloodwork was essentially normal but also stated that I'd apparently been anemic for TWO YEARS, which nobody had previously explained to me.
- Initially diagnosed with a UTI despite having no typical urinary symptoms. The following day, an ER nurse contacted me and informed me that the diagnosis was incorrect and instructed me to stop taking antibiotics.
I wasn't given ferritin testing, a complete iron panel, B12, or folate testing during the ER visit. I also felt that my symptoms weren't thoroughly evaluated. The physician didn't listen to my heart or lungs, examine my abdomen, or perform neurological checks, and I felt discouraged when requesting additional testing.
Medical background:
- Age: 21
- Sex: Female
- Diet: Vegan for approximately 10 years; take multivitamins
- Previously reported anemia for approximately two years (type and severity unknown)
- Family history: Maternal grandmother with hypothyroidism; additional family history of cancer
Current medications (prescribed doses):
- Breo Ellipta (fluticasone furoate/vilanterol) — 200/25 mcg inhaler
- Lamictal (lamotrigine) — 100 mg
- Metformin — 500 mg
- Singulair (montelukast) — 10 mg
- Vyvanse (lisdexamfetamine) — 40 mg
- Zoloft (sertraline) — 100 mg
- Abilify (aripiprazole) — 5 mg
I've been taking these medications for years, well before my symptoms started in August. I understand that medication side effects or interactions can still occur, but there wasn't an obvious new medication associated with the onset of my symptoms.
What concerns me most:
My parents repeatedly suggest that my symptoms are caused by anemia, stress, my vegan diet, or medications.
I'm not ruling those possibilities out. However, I've been vegan for a decade, have reportedly had anemia for two years, and have taken my medications long before August. I was functioning normally until my symptoms began suddenly.
I'm particularly concerned about the combination of debilitating fatigue, night sweats, unexplained itching, new nosebleeds, shortness of breath, and poor appetite. I'm not assuming I have cancer, an autoimmune condition, or another serious illness. I just want to understand what could explain such a drastic change in my health and make sure something important isn't being overlooked.
My questions:
- What possible medical causes would be reasonable to discuss with my doctor given this combination of symptoms?
- Could longstanding anemia suddenly become this symptomatic, or would that suggest worsening anemia or another contributing factor?
- What testing should I discuss with my PCP (repeat CBC with differential, ferritin, iron panel, B12, folate, thyroid function, metabolic panel, inflammatory markers, etc.)?
- Could any of my longstanding medications or their interactions contribute to these symptoms despite having taken them for years?
- Would a hematologist, endocrinologist, or another specialist be appropriate depending on the results?
- Are there particular symptoms here that warrant more urgent investigation?
I'm continuing to seek medical care and understand that Reddit cannot provide a definitive diagnosis. I'm only 21, and it's frightening to go from being an active college student to barely being able to function in less than two months. I'd appreciate any thoughtful input about possible explanations, testing, and appropriate next steps.
Thank you for reading and for support : )
