Little allergy bump

Hi, I've been searching online everywhere and have not seen anything like what I'm getting. On my upper calf on the side of my leg I get a little hive like bump that comes up every once and a while but does not last long. It looks like a mosquito bite, but I know it isn't becuase its been coming in the same spot for years. It itches a bit, but not too bothersome. I'm so used to it I don't notice when its up sometimes. Most of the time its not there, just normal skin, no sign of anything. I'm just curious if this is just an area that reacts to a toxin in my body while the rest doesn't, or a sign of food allergy that could get worse?

Hello,

Do you get the rash only in summers? Do you stay out in the sun for long?

It can be a Golfer’s vasculitis heat rash, a red rash on the calves of many walkers. It often starts above the sock line and makes red patches and splotches up the calf. In that case, taking bath with cold water after staying in the sun or applying cold wet towels may help.

If your legs are itchy during or after exercise, with no relation to heat, you may have exercise urticaria.In such cases, antihistaminics and not exercising on warm or humid days may help.

You may apply calamine lotion and cool compresses on the rash. It may help.

Pls see your dermatologist if the condition does not improve.

Regards and pls do keep posting.
