My son son suffers from a aggressive form of Burgers disease. Kidney function 4 weeks ago was at 28%! Right now, even so it is very warm outside, he feels cold enough to wrap a blanket around his body. His temp is 95...other symptoms: tired and feels worn out...no swelling or any other symptoms. My son is 45 years old, I do worry about him! Pls. let me know if I should take him to Hospital. (Btw, he is seen at the VA Hospital in Albuquerque, NM)Thanks you!
