It is more than a year since there is reoccurring of bumps on my butt. Unusual thing here is, it doesn't show pus, it just swells and circumference around the bumps increases. After a week or so, the bump flattens. And after some days, the process starts again. I had consulted general physician, the medicines does flattens the bump but it doesn't stops from reoccurring. The pain is unbearable, as it is on bump it is not easy to sit and to any work. Please suggest me remedy. I don't know who is specialised in this one or which doctor to approach.
