The road to recovery from PCS is a rocky one. It is a roller coaster ride. I have had regressions/new symptoms appearing out of the blue, months into it. You are still in the early stage of recovery, so do not despair.

That being said, I have noticed that my body has gotten very sensitive to any types of medications and even supplements. Stopping the medication could have been too much of a change/shock to your body.

Mark is an expert. (in my experience, he knows more than any GPs, or specialists I have come across).
