I have pitting edema in lower legs, lethargy, unexplained weight gain and bumps under the skin on shins, forearms and outer thighs (very tender) and sudden, brief pains occurring randomly around my body that is increasing in frequency (like jabs, sometimes feel tingly). (I'm 46 and also have problems with non-allergic rhinitis, memory, IBS, insomnia, and sometimes have shortness of breath and chest pain--heart checked out fine via stress tests and holter monitor, although I had two abnormal EKGs--and I take thyroid medication). Could all these symptoms be related? Any thoughts on the cause? Thanks!
