Hi mac,
I'm sorry your not feeling good t the moment, it's a bit worrying about the HRT patches and the oestrogen not allowing the thyroxin to convert properly if your on them, I have been on the patches for eight months now and have just been diagnoised with under active thyroid,and am on day three of my thyroxin 25mg, surley my gp would have said if there was a problem with the patches, I would hope! I kept trying to tell my gp that I had thyroid problem for about a year now, but every blood test came back normal or borderline,
But this time thankfully they indicated I was under active, thank god I can hope to feel better soon, I had all the symptoms too, cold hands and feet, cold most of the time, dry skin,exhaustion,tingling lips,put on weight, and oh yes the big one constipation!
I'm sure if you see another doc in your surgery,you should be able to go back on HRT , just go in and be firm and say you have decided this is what you want, I'm not sure the patches would be causing the migraines as they are recommended for people who suffer from them,
Could your high level of thyroxin cause these migraines? I'm new to thyroid side effects,but everyone is effected differently.
I hope you get to feel better soon.
