Hi there, I do not know whether you will be able to help me? i so hope so as im in alot of pain everyday with my hands, fingers, wrists, arms and blistered tongue and mouth and very painful itchy rash. Every summer i get a heat rash all over my body and nothing stops the itching. I have tried antihistamines and nothing works. i itch until i bleed. However, after my holiday in August my hands and fingers and wrists are extremely painful. I cannot straighten my fingers at all now as too painful. i get pins and needles in them and electric shock sensations, especially at night during sleep which wakes me in tears as so painful. they are swollen and my wrists hurt and keep clicking all the time. my thumb is also extremely painful. i also have recurrent blisters appear everyday on my lips and my tongue is very sore too. i have the rash on my knees at the moment and back of my hands and arms. this usually only happens in the sun. im am very tired and suffer anxiety. i am having to get someone to type now as too painful. I have been to my gp for blood tests for lupas, and arthiritis to which i have neither of these. im at a loose end and cannot bear to live with the pain. please advise. thank you. I forgot to mention that i am a female aged 41.
