My son is 19, a few years ago he started to have small spots on his scalp which flair up every now and again, his scalp becomes red with patches of tiny spots some with pus. Over the last couple years it has become a lot worse and he has had shampoo and steroid lotion from the Doctor, this made it worse but a course of antibiotics cleared it up but, as soon as the course is finished the spots return within a week or so, the Doctor thinks it's folliculitis and sent off a swab but nothing showed up. He surfs and swims so is in the water a lot. He is now waiting to see a dermatologist but in the mean time his scalp is red and inflamed with clusters of lumps which are very sore, some without heads which look shiny, some with yellow/white heads which are also very sore. His whole scalp hurts and feels tight and is very painful. Can anyone help?
