hi my husband is 34. has a good health record as far as we know. his family does have alot of medical background such as, Diabetes, fake hips, as well as brething problems. he is about 5'6 and weighs about 130. In the last three days he has been getting a rash all over his body that is very itchy. As well he has been getting hot/cold flashes and migrane headaches. The headaches have been every morning whe he wakes up and the headaches have been ever day for about four days. About a week ago we noticed a strange lump on his hand that moves around and is very sore to touch. As well he is getting very bad pains in his joints and muscles and has been very over tired for about a week or so. does anyone know what this could be and if all these symptoms relate to one certain problem?Please help.
