    My 38 year old son has been having fever over 12 days. He also has muscle and body pain. The blood test did not detect anything. He has been taking antibiotics but that has not cured him. He takes Epsom salt bath. Also tried vinegar water compresses on his legs, arms, head, neck and chest. There is constant temperature which does not come to normal.

      Persistent fever for long duration needs detailed investigation. X ray of chest and sonography of abdomen are valuable tests that may help to diagnose the underlying ailment. Also a repeat blood test may be valuable. Fever for long duration may be due to typhoid, tuberculosis and many more ailments. Once the ailment is diagnosed, treatment will become easier.
