have a rash on both of my arms and lower part of my legs with a stinging needle sensation. i have gone to a derm. and was put on a steroid cream, which help with the fever and the swelling that was occurring.  it actually went away for a couple of weeks and is now coming back.  any suggestions?
Hi, You said you have rash on extremities with stinging sensation. Most probably the rash you described might be militia...as there is stinging sensation.  There may be reddish microvesicular rash. Other possibility is purity...as the lesions are relapsing. It is difficult to pinpoint exact diagnosis with this little history. You personally consult dermatologist. Blood tests may be done to rule out internal diseases. You might get relief after taking antihistamines like desloratidine. Soothing lotion of calamine with lover might improve the disease. If needed, steroid in tampering doses may be taken. You might feel better in few weeks. I hope you got my answer. Thanks.
