since myxedema is not fat, losing weight won't remove/shift it.
A post from 2 years ago and some other obscure links led me to the supplement NAC, N-Acetyl Cysteine.
Also aerobic and dancing to get me sweating also seemed to help.
These two measures combined to help me lose 2 inches off my arms and also weird mucin deposit at the center under my breasts, my back and neck hump.
It was so awful to fix my thyroid and adrenals (natural thyroid and adrenal supplements) but still have unslightly looking deposits.
Most people assume it's just fat.
What angers me is that the average modern Doctor doesn't know about myxedema !
I found textbooks from 1917 that were more helpful in helping me repair myself.
