I had shoulder surgery 8 days ago. The pain was manageable and I stopped the percoset etc. after 4 days and am only taking advil as needed. However, I have been troubled by sores in my mouth. have been rinsing with hydrogen peroxide, diluted, 2x a times for 3 -4 days, but its still bothering me. Although a bit better, it is not clearing up. For the past 2 days have not been eating/drinking acidic foods, i.e. coffee, citrus, tomatoes.
what's going on? and what can I do about it?
