hello,i have hashimoto and i take 50mg t4.Usually the summers i m having very strong and weird migraines,sometimes i loose focus and part of my vision,some small panic crice,sometime can also loose the feel of my arm(s) .Very rare i had speech-language disorder.After strong painkillers and sleep i m coming back to almost regular.Im thinking of any hormonological problem,or maybe an oldest injury in the back of my head(15 y ago) with concussion and speech-words disorder for the first time.Do you think of anything?Any suggestions?Thank you all. Regards
