I've recently developed this. I'm taking prescribed steroids which is helping a bit with the current crop of bites but I don't want this to keep happening. Is there a way of overcoming it or should I just bathe in deet for the rest of my life? As well as the weals and sores I actually felt quite ill at one point earlier this week and it's just miserable. Is it worth asking for a referral to the allergy clinic or something? Pic attached to give an idea of what I'm talking about. After a couple of days they bruise.
