Earlier he use to get sores quterly, but eventually the frequency increased and now he has one or two all the time. We consulted few physician and one GI specialist. We did all the suggested test including colonoscopy and HIV test, but all is clear. All Doctor said that it is due to stress, but he don't feel so. We are really concerned as it getting worst and worst. The only treatment is just to get symptomatic relife by some ointments and mouth wash. Please suggest anything helpful. Thanks!
