Open sores anywhere for nine months is not a good sign.
I do not know what is causing them but taking the scabs off is not a good idea.
You may need antibiotic treatment. Schedule an appointment to be seen as soon as you can. I would suggest in the mean time, putting antibiotic cream on the sores and covering them with bandages or gauze and cotton pads (regular cotton balls will leave fibers in the sores).
Please let us know how you are.
