Hello, I'm new here and starting down a frustrating path that I see in other's posts. I have extreme fatigue, hair loss, intolerance to heat, palpitations, tachycardia, arhythmia, increased bathroom visits, sometimes can't breathe (feels like an elephant is sitting on my chest), tinnitus, rosacea, back pain, etc., etc. The symptom that's driving me bonkers is a tingling burning sensationf rom head to toe. The tinnitus is pretty rough too. I seem to have a combination of hypo and hyper thyroid symptoms. A doctor said that my thyroid was full of nodules (by feeling it). 2 weeks later another doctor said she didn't feel any. Is it possible that nodules would overproduce, causing hyper, then stop producing, causing hypo? TSH came back normal, but my cousin's did also and she ended up having her thyroid killed because of over-producing nodules. Thyroid problems run int he family.
