My sister is bed ridden, she has huntingtons disease and is not mobile. We have a PSW that comes through the day to help her. Over the past few weeks we noticed she s developed a rash on the race, red swollen patches on her cheeks forehead and neck, it s flakey and at times very itchy. Now her eye is swollen from her eye brow and around the whole socket, puffy. She cannot speak very well so she can t tell us exactly the degree of the symptoms she s feeling but from what we gather she is constantly itchy. We ve been using calamine lotion, aver no anti itch and this brings temporary relief i guess there could be a number of conditions causing this and since she s not mobile we are having a hard time getting her to a dermatologist, never mind a referral. We had a doctor come who does house calls a week ago but he didn t offer much help other than, do a process of elimination to see if it is an allergy. My question is from the description could you recommend a treatment for relief to try?
