I have painful, immovable lesions on my scalp. They are very troublesome. I can t seem to leave them alone. Some bleed, and then go away for a couple of weeks. I have two that will not go away, and are painful. Any help would be appreciated. I am 58, female, diabetic type ll (controlled with diet and medication). I also have painful joints in my hands and knees. Thank you for your time and attention to this request.
