I am going to respectfully agree with some on this thread that are suggesting that TRT may not be at the root of all your issues. As I mentioned before, I have not read the entire thread (it's long), but I think you mentioned fluid retention, concerns about your kidneys and lasix. I also read previously that you are very leery of the medical establishment. I may be wrong, but this would suggest to me that you are possibly self treating with lasix to address your swelling? Forgive me if I misinterpreted the fact pattern. But, if you are in fact self treating with lasix, you can really insult your kidneys and even cause kidney failure.
Could it be possible that TRT triggered something unpleasant years ago, but all the subsequent interventions (medications, supplements, etc) have caused a complex cascade of problems?
Numbness in both hands can caused by a LOT of things. Common things are common. Most commonly, cubital tunnel or carpal tunnel cause hand numbness. But, this would usually involve only certain fingers/parts of the hand. If it is the entire hand, perhaps it is a peripheral neuropathy (which in turn can be caused by a million underlying entities).
You are frustrated and upset. I wish someone here could suggest a magic bullet to solve your issues. But, (and this is only my humble opinion) I think you would be better off expending your energy on finding the right physician than chasing all your symptoms yourself. I would start with an internist. The right internist will know when a condition is better evaluated by a specialist and refer you appropriately.
