Hi im back on levothyroxine after a hospital visit with suspected steoke. It wasnt a stroke but put down to being hypothyroid TSH 4.73 thats the only result i was given. I had an MRI too and they said it was ok. (Big relief) ive been back on my original dose of 25 mcg for a week now still feel crap and tearful, now have headaches and agitation too. Im not normally an irritable person. Think im just fed up of never feeling right. I had a letter this morning to say go in for a visit to the GP.
