I have been ill for 3 years. Fever upon activity, I had a fistuai and abdominal infection one year ago, but the fever comes back if I move around to do easy house hold chores, goes to 101 and higher, wirh abdominal pain and fast heart reate. I have had heart infection before. I see Drs. at KU medical hospital, Kansas city, Ks.
Hello, Fever with pain abdomen could be signs of infection, but if you are getting frequently, you should be examined thoroughly and get your complete check-up done i.e. if you have not got them done in the recent past. Please consult your doctor. Any other queries please let me know. Hope I could help you.  Thank you.
