I have been suffering from crippling tendonitis in both Achilles for about 6 months now which has become really debilitating, I am also suffering from pains in my thighs, mostly my right side and my hip. I have never known anything as painful and it is affecting my mobility. I am undergoing tests for "mild" hyperthyroidism, and currently awaiting the results of my isotope scan. Has anyone else with a thyroid disorder suffered with these symptoms or are they a symptom of something else completely? My life doesn't seem worth living most days, I'm in my 50's but most day's I feel 70!
