Have been tired alot lately and I noticed that my underarms are a bit yellowish(no swelling or pain), anyone have any clues as to if this is related to cfs or possibly something else.
Also still have this numbness and tingling on both sides and having emg tests bloodwork noone seems to have an answer. Lately my left arm is numb and weak(intermitting)

Could be a thyroid, adrenal, or liver problem. Your blood tests may have been screenings? What does your doc say about the yellowing?

Have you tried methyl B12 sublingual for the tingling?

Best wishes.
