I was bitten just above the ankle.

Tags: Allergy

I was bitten just above the ankle three springs ago by what may have been a Blandford fly. My leg swelled up and I was left with a brown discolouration.

A year ago I started doing a pilgrimage in France and Spain which entailed walking 25km average a day. I have since been diagnosed with exercise induced Vasculitis. Yesterday after a walk the bite area was bright red after a 2 hour walk, coincidence or is there a connection?

The answer

Exercise induced vasculitis (EIV) causes a red rash on the lower legs after a long walk. The rash can itch or burn. It mainly affects women and occurs after walking (or long distance running) in hot weather. It fades on its own after a few days and as a result is often left undiagnosed. It can be linked to other auto-immune diseases but most cases have been linked to otherwise healthy individuals.

The area of skin that was bitten has been left slightly damaged and discoloured. I am not surprised that this area would again be targeted by the rash of the EIV. If the rash does not settle then show it to the doctor again.
