Having Been To Two Dermatologists, I'm No Closer To Healing

Having been to two dermatologists, I'm no closer to healing tbis skin disease/condition. Neither one performed a biopsy. I have had this it hing/burning rash on my face, neck and arms. It consists of raised reddish areas. I've had ringworm before and know this rash is not ri gworm. I reeived a shingles vaccine, so it's not shingles. It just began about 1-1/2 years ago. It comes and goes. It is somewhat weepy. The pustules consist of clear liquid and are small compared to ringworm. They are splotchy andcan be irregular looking also. I've been prescribed hysdrocortisone cream. It really doesn't treat this rash. As the cream wears off, the itching/burning begins again. What do yoy suggest? Can you recommend a dermatologist near my house who will finally detect and successfully treat this rash? Thank you for any information you have. It's driving me crazy.
