Possible autoimmune issues, need answers

26 year old white female 5’9” and 270 lbs Pennsylvania, United States

Preexisting medical issues: PCOS, depression, anxiety

Medications: metformin, wellbutrin, lexapro, blisovi (birth control)

I’ve been suffering with chronic body pain and aches for almost a year now. It started in my left knee, then my right, and now is my entire body. By the end of the day I can hardly move and am driven to tears. I am also extremely fatigued, basically lethargic. I have gastrointestinal issues (nausea in the morning, diarrhea in the morning) as well. There are times throughout the day I can’t open my eyes I’m so tired. I’m desperately in need of answers as I can barely do basic activities anymore.

Important info:

I had X-rays done on both knees and they came back normal

My blood sugar and A1C are completely normal

I tested positive for ANA (antinuclear antibodies)

I have elevated C reactive protein (18 was my number)

I have an appointment with a rheumatologist in March but am suffering so much in the mean time, please help with any guidance
