For the past few weeks I have been suffering from a rash type thing that s like small little pimple like bumps that starts in my head and goes into my neck, back and my ears it gets so bad that I scratch till it bleeds. Haven t used anything different than I ve been using before. I have swollen lymph nodes in my neck that swell and then go down, and I also get reoccurring abcesses. Have had tests for thyroid all normal. I have noticed I ve had a lower anger threshold (not sure if it s related ) please help.
