I have these sores on my legs,upper arms,upper back,font of theighs also on my knees... I went to a PA she had worked with a dermatology for years, I could not see the dermatology at the time.. she did an biopsy,and she said that those sores were ulcers..i have quite a few of them...she gave me a cream and itching..and 2 hydroxine at nite..now I been on these medicines for 2 weeks, some are drying up but the small ulcers keep coming..i am a diabetic,very well controlled...I called the doctor back, and she not say much, and told me to keep doing what she told me to do, and go back in 3 weeks again and see her...I feel like we are missing something, cause those ulcers just keep coming back..since I seen her last I have faithfully doing all she told me to do...they are sa-mall and round, and I can t help but to scratch some of them..and when I do nothing comes out at all, but the sore has an evenly round mark inside the sore, after I scratch some..i do not know what to do ? can you give me some insight help or what ?
