Last month I had brown stretchy and black discharge for three days and then it stopped. This month again I'm having the same thing It started from 10th April and continued till 12th April and it's smell was really disgusting. Now I'm also having off white grayish discharge and it smells acidic. I have never experienced this type of discharge before I used to have white discharge. I also consulted a doctor she told me to take Sompraz 40 and Flagyl 400 but there are no changes. My back hurts like hell. Please tell me why is this happening? Do I have an infection or is this some sort of disease?
