Hi I currently take 125mcg of thyroxine per day but a few hours after I take it I get a very bad headache at the front of my head and sometimes behind my eyes. It feels as though my brain is bashing against the front of my skull. I'm not prone to headaches but it always seems to be after I take thyroxine. Also I came over a little heady/dizzy.
Is it possibly a T3 conversion issue or am I not giving enough time for the new increased dosage to work? I've been into my increased dose for 3 weeks now.
Any advice would be greatly appreciated.
