Hi there , i just want to get some opinions on a rash ive had on my arms for 6 weeks . It’s itchy, it can get hot , long sleeves aggravate it. I have been using E45 and hydrocortisone which gives short term relief only . I don’t have lupus , i have Sjögrens which can also cause some skin problems. I haven’t been to the gp yet as I’ve hoped it would clear but i should get an appointment sorted as i have occipital pain mow as well . Do you think it is eczema or autoimmune , I have had episodes of eczema in the past which settles with treatment .
