I have random swelling in various different places, mostly in my feet and legs although it has been noticed in my arm ,head and body sometimes I would describe them as welts but usually about the size of an egg. Also I have a low grade fever this is mostly by the end of the day. I have been to the doctor and he took 4 blood samples, most came back in the normal range although he said one indicated some inflammation although he could not determine the source. I have body aches and fatigue. I am a 61 year old male farmer, my prostate exam was good and I had a colonoscopy about 1 year ago. I am 6 feet tall and weigh 205. I take 40mg of crestor and 5 mg of simistyatan, my blood pressure is usually less than 145/85 and my pulse is about 63
