I've been diagnosed now for a couple of years, but like most have suffered for years, I don't get joint pain. My main complaint is debillitating fatigue. Over the last month I've started to experience breathlessness which is like breathing at high altitude, the air feels very thin. I phoned my rhuemy who said not to worry. I go to the gym but struggle on the running machine (I walk). It's mainly in the upper part of my chest and is there constantly, even at rest. I've also discovered swollen, painful lumps on my jaw line. (not seeing rhuemy about that for another month). Every few months there appears to be a different symptom which causes me immense paranoia. A few months ago I had a sore boob and was convinced I had breast cancer. My doctor sent me for a mammogram (I'm 40) which was clear. Now I'm convinced the breathlessness and lumps is leukeamia! Does anyone else suffer with this hypercondriac type paranoia? I'm a paramedic who is usually very level headed and grounded! I think being on Azathioprine has added to the paranoia, the thought of my immune system not protecting me from grim stuff makes me panic.
