I am having the most peculiar symptoms with no real answers. Out of the blue one morning I had a rash on my inner arms, and terribly itchy for that day. After showing that evening, it was all over my arms, but quickly faded and never has repeated this. My first thought was it was my Levoxyl, but I have been taking it for nearly 5 years (thyroidectomy for cancer), and taking that particular pill (88mcg) for over a year. My dosage had been increased slightly four weeks earlier by alternating the 88 mcg every other day with a 100 mcg. The rash faded, but returns nearly every morning and usually fades after about an hour. My endo put me on Synthroid for about a week, just in case, but I had a terrible time with the Synthroid, sore tongue, cheeks breaking out, hot flushes. So, switched to Levoxyl 50mcg, no dyes, alternating 2 50's one day, 1 1/2 50's the next, which brought my dose back to almost the 88 mcg I was on originally. So, three weeks on this dose and I still wake up with a rash, red, pin-prickly looking to kind of a red-flushed look, barely itches, that fades after about 30 minutes to an hour, doesn't seem to increase when I take my Levoxyl in the morning after getting up, and my tongue and inside of my mouth peridocially is terribly sore and sometimes feels "scorched" and my face feels weird a lot of the time. An allergist said he doesn't think it's the levoxyl, and I am wondering if I have a B12 deficiency. TSH is good, below 2, but T4's were elevated at 11 about 10 days after starting lower dosage with the 50 mcg's. I'm so confused and just miserable with these symptoms. Does anyone have any solid ideas? I would truly appreciate it.
