Suggest Remedy For Itch And Rash On Shoulder

HI,I have had a severe itch and rash on my shoulders.I went to dermatologist and he took biopsy and said I had follicular something and told me there was no cure.He said the only thing to help was a low dose psychotic drug that he couldn't prescribe but for my family doctor to.When I told my doctor this he told me he didn't know what I was talking about.When I went to family doctor for some kind of relief,they treated me as if I was mental and told me to see a psychiatrist.Dr please,I am not mental,maybe alittle stressed.I have had this severe itch and when I scratch,small circular wounds appear.It is very itchy.I have had this for over a year.What do you think?I have been bitten by ticks,do you think that may have anything to do?Thank you...
