For the past 2 plus years I have had a flat red rash that starts on my neck and works it s way around the whole of my neck. It becomes hot, sore, and can be there for days. When it does go down I can pull little bits of skin off - a bit like sunburn . It s appearance looks a bit like I have been burnt. The skin can become taught. It can come and go on it s own accord. It normally starts when I feel my neck tingleing and some timed it can be itchy - quite itchy when it s completely around the whole of my neck. The doctors haven t been able to advise what it is and just tell me to moisturise it.
Hi there Julia First, dermatology is a visual field & as such would greatly appreciate a clear digital photograph of the lesion uploaded on this website using the upload data icon. Should you wish discretion, feel free to use our premier ask-a-doctor feature & directly get in touch with moist or any other dermatologist. From your clinical description, it does appear like a photosensitive skin eruption. Is there any family history of porphyria or any other photosensitive disorders or any genetic ailments e.g.  Chat Doctor.  Do go across to a dermatologist nearest to you & am, sure it will all be sorted out! Cheers & good luck!
