My family have large round sores that never heal.These sores turn black, itch often. Black specs like pepper and white eggs come out of the sores frequently. We feel a sting when we are bitten but can't identify the pest. We had birds in our attic and have sprayed for mites. We have been placed on antibiotics which helped but didn't heal them. Our family Dr. keeps treating us for staph but nothing has helped. The family dogs seem to have this condition to. It seems to be affecting our brains and energy levels to. Where do we go from here?
