my 14 year old daughter has had a large pimple on her nose for 5 years,on and off. recuirring. Several times she was able to pop the huge zit and makd it go away, foir awhile. Onece the dr. injected cortizone, and it did go away after a couple days. this may be a cyst, the more I read the more I think it is. She was just diagonised with PCOS, and her ance is out of control, dr. gve her bc pills, but tuesday we have appt. with endocronoglisit. (sp) so hopefully they will help with a more agressive plan.
