I have had problems with inflammatory polyarthritis, osteo, fibromyalgia etc for over 20 years. I have never formally been diagnosed with hypothyroid because they have always gone by TSH in bloods, but when my old GP began treating me with T4 things improved very quickly. I was on T4 for years and everything was ok. Then a few months back, after I had changed surgeries because my old GP left, things went Pete Tong. I became very ill. After taking advice from the forum things have improved a lot, but one thing is bothering me. Since things went downhill if I cut myself it bleeds profusely and is difficult to stop. I mentioned it to the new GP who didnt seem overly bothered. Could it be related to low thyroid, or a deficiency of some kind please?
