I have been on 75 thyroxin for 8 weeks now and am due a blood test next week. In the eight weeks i have had a recurring sore throat, particularly down each side, my ears itch and my asthma symptons have become much worse. My eyes feel puffy and i have a milky like mucus at the top of my nose. I went back to my gp after the first four weeks and she just said we'll see what happens after your eight week blood test. Am i always going to feel this miserable?
