Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.Pyoderma gangrenosum
is predominantly a disease with superadded infection. It needs a proper control of infections. The best would be to get a culture and sensitivity of the wound and then start the antibiotic accordingly.
Further the problem of headache is understandable. If there a severe infection in the body then there is plenty of inflammatory mediators in the body leading to such headaches
. You should take some mild pain killers like paracetamol
to help with the headache.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
