For the last few days I have been experiencing a different pain - it feels like it is coming from my bones and sometimes feels as if they are on fire! I am struggling to get around at all now. I have been on 7mg for some time now. Don't know if it's the pmr, the pred or levothyroxine as I had total thyroidectomy 10 years ago due to cancer in thyroid gland. The only change is that I started exercise on GP referral at the gym 2 weeks ago, but have gone very gently and only done some walking and cycling exercises. Any ideas please?
