I was diagnosed with Hashimoto's Thyroiditis in 2004, in spite of not having any of the antibody tests to my knowledge... my GP merely presumed this diagnosis and I was treated accordingly with replacement Thyroxine (the cheap and cheerful stuff...). I had a cold about a year ago, during which time I lost my voice for nearly 6 weeks and found it very hard to fight it off. I then started becoming very breathless at times and was diagnosed as being asthmatic in June. Although the Salbutamol inhaler works as a brilliant reliever, I found that the Clenyl Modulate steroid inhaler negated the use of the salbutamol completely for the 6 weeks I was taking it. However, I had a reaction to the Clenyl inhaler which meant I was constantly battling a stuffy nose which interfered with my ability to smell, taste and worst of all, sleep. I have now come off the steroid inhaler and am taking Singulair50 instead, but have now once again, caught a cold which after 4 weeks seems to have no intention of clearing up at all... Is there a connection between my hypothyroidism, the asthma and my apparent lack of ability to shake these bugs off? I am currently taking 100mcg of thyroxine, but suspect that this is not having any effect on any of my symptoms, especially my weight, at all. My last bloodtests all came back, surprise, surprise... 'normal'!
