Seeing a local doctor who competently practices in the field of functional or mitochondrial medicine might be covered by insurance if that physician is conventionally credentialed (eg. as an M.D. or D.C.) Might you consider looking into some of the research and writing out there today on the possibility that many of the neurological aftermaths of COVID look remarkably similar to syndromes and symptoms that have been associated with sudden depletions of particular B vitamins? Another line of study is about whether COVID may, in some patients, do something to impair our ability to absorb vitamins (especially thiamine/B1), and this has sparked some patient-driven exploration into whether some degree of B1 supplementation may begin to normalize long COVID patients. B1 supplementation protocols are popular in relation to several non-COVID-related chronic illnesses, and itś important, before starting on B1 supplementation, to be keenly aware that some people need and can tolerate lots of thiamine (usually in HCl form), while others are sensitive to B1 and do better starting with very conservative doses that may gradually increase, if tolerated. If this interests you, please, if easy, see if you can pull up several long posts I have shared across multiple long-COVID subject categories here, on this topic. . . Most importantly, do not assume that you will never recover your senses of taste and smell. Sometimes, solving the mystery of why this has happened, in your case, based on your health history, can be all it takes to shake things up and get you on a healing track . . .Having a great functional medicine doctor working with you on this, moreover, will make for even greater success.
