I have just found out I have a hyper thyroid. Along with a goiter and nodule! About 6 times over the past several weeks I have had anxiety attacks so bad (never had them before) and what I get is like a dreamy feeling, very anxious gittery stomach, nausea, sweating/cold chills and my body will get these burning sensations. My arms, chest, neck, head, face all feels like i have tingle lotion on for getting into a tanning bed. Freaky...all anxiety related!
Very common with hyperthyroidism, be patient and do what the Dr. tells you and it will get better
