Strange sudden rash on arms and legs only, it is slightly itchy and not pus filled. The rash is all over my arms and legs, no patches only some of them turn into hives. I don't think its contact dermititus but it looks so weird. The bumps are slightly raised and red but not blotchy, any suggestions on what it could be.

Could be time for a walk-in clinic or a visit to the doctor's office. Regardless of what we say here, they're the only one that will be able to prescribe any sort of creams or what not to help the condition.

So instead of waiting for us to respond, I would just go to the doctor or walk in clinic.
