My 9 year old son had been diagnosed with neutrophilic dermatosis ( pyoderma gangrenosum) also with splenic and pulmonary abscess previous arthritis ( sweet syndrome) his medication he is on is Adalimumab, cyclosporin, prednisolone, pain killers, my son has now got a lot of pain in his penis and testicles he has had a pyoderma close by about 3 months ago but it was switched off! Could the pain just be part of his illness or growing pains or could it be something else?
