I don't know of anyone particular in Doha but my sister had a similar prob in SL so I know you need to see a skin specialist. I have been to some at Hamad but not for the same reason as yours. Inshallah if the skin specialist feels its nothing for concern alls well. But if,God forbid, she has any concerns she will then likely refer you to another doctor who specializes in this department. And may require a minor surgery.
