I Am Going Out Of My Mind, I Have This

I am going out of my mind, I have this horrible rash on my heels the doctor has not been able to do anything for me she just keeps prescribing meds that have not helped. It seems to get worse than better. The steroids have not worked, she has not sent to lab to see what has caused the flare up. I have never had this ever til now. I have had this now for 9 months. I have spent a fortune and nothing seems to work!
