I’m on week 7 post acute infection and have similar thing. I’m going to a specialist to identify if mine is nerve/muscular etc. I already went to cardiologist and all that was good.

I recommend seeing a specialist as a referral from primary to start seeing what might it be or at least eliminating what it’s not.

Also I’m a member of two non-moderated random long hauler Fbook groups (aka, not medical advice so have cynical eye)…but I’m reading and seeing more about antihistamines being an issue related to my symptoms. Many find pains in legs and arms alleviate with an antihistamine H1 and/or H2 blocker (Allegra/Zyrtec/Claritin or Pepcid). Again not medical advice, but something to ask your doctor. I’m on low histamine diet and my symptoms in arms and legs seem to improve. I was diagnosed with skin fungal infection from antibiotics in ear infection and taking meds and took one tablespoon of apple cider vinegar in tall glass of water mixed together. Two hours later my entire face and scalp was super itchy and I realized although apple cider vinegar is great for fungal infections it’s high in histamines (lowest in histamines if vinegars but still high). I’m meeting with my dr again next week to check progress on fungal infection and also with dermatologist to confirm my skin infection isn’t something else.

I hope you continue to feel better. It is a bit overwhelming to have all these symptoms persist. Wishing you good healing soon.

@outdoorslass, I add my welcome to @tiredmommy's. You'll notice that I moved your question about muscle and joint pain post COVID to this existing discussion:
- Joint inflammation and muscle pain after COVID https://connect.mayoclinic.org/discussion/joint-inflammation-and-adults-possibly-from-covid/

@aztennisguy @kd1974 @chrism have also reported muscle and joint issues with and without exercise with long COVID.

Outdoorlass, are you experiencing additional long COVID symptoms? Does reducing the intensity of your activity allow you to exercise?
