I know you get a lot of advice, but I just wanted to chime in with one more thing. Traditional Chinese Medicine can be very powerful in a case like your’s where something is off but nobody can figure out what it is.
Basically, over 6,000 years or so, very observant Chinese doctors created a set of theories about health through observation, noting some patients exhibited signs of a faster metabolism, some slower, some hot, some cold, some wet, some dry, and then they divided those up more by five types of disorders they likened to dysfunctions of five systems in the body, and then they divided each of those into types of dysfunctions.
That was combined with observations of how herbs affected those same systems, with an eye to finding herbs that did the opposite of whatever was wrong, to push the body back into the balance point where health lay. Along the way they noted physical injuries in battle to various parts of the body could have similar effects to the herbs, and that ultimately became acupuncture.
I’ve seen the effects of it firsthand, and although the process is unscientific in terms of Western modern medicine, a skilled practitioner who has developed the power of observation it cultivates, and knows how to apply the theory can be scary-brilliant in their ability to understand how to correct what is wrong, in a way modern doctors will scratch their heads at.
If I were you, I would look for a Chinese trained practitioner of TCM, who uses both acupuncture and herbs, with at least a decade and a half of actual active practice, and ideally two or three decades. Just try them for four or five weeks, in which time you should see a mind-blowing difference or not. I would go in expecting to try two or three practitioners before giving up on it, as there is a tendency for them to slip into specialties, or specific types of imbalances they are mind-blowingly ood at identifying and treating.
I’ve personally see an expert in it do absolute miracles on multiple people, and I would definitely try and add it to what you are doing. Things like edema and immune dysfunction are right up their alley, and it would be done on top of everything you are already doing which works.
Good luck and God Bless.
