bellableu125, Bless you. I went to a COVID Recovery Clinic and got the diagnosis of Long Covid. I have COVID twice. I then went to an Integrative Medicine doctor who recommended a lot of supplements. I could not tolerate the infusions to boost my immune system and help with the inflammation. I have some of the same symptoms that you do, but, not all of them.

I am so sorry you are battling so much. Doctors were not prepared nor are they trained in how to treat LC.
You have to be your own advocate on this I have found. There are a lot of good recommendations on here of people battling the same things you are.

COVID wiped out my B12. I was having tingling/burning (parasthesia) in my hands and feet. My body does not
absorb the folates very well. I am on a B12 injection weekly. The parasthesia is gone and I am so grateful.

Praying for you right now to get better. Blessings & Prayers....
