I am Hypothyroid, some days I feel really stiff and ache, but I just say "I'm fine" recently I have a real gravel like feeling in my throat, when I wake up in the morning, if I laugh it really hurts and I cough. I had a head cold maybe 6 weeks ago and had a sore throat then, but that should have gone by now. I think I might make a routine appointment with my GP anyway. Does this just sound like a minor throat infection or should I be aware of something else happening. I am on 75mcg Levothyroxine and Lanzoprazole!!!!
