Hi. I Got Bitten By A Horsefly Two Days Ago.

Hi. I got bitten by a horsefly two days ago. I always react quite badly to bites but this has happened more so this time. The bite was on my lower left arm and the whole elbow joint has swollen up. It has gone down slightly this evening but my hand and wrist has now swollen. I am taking anti histamines and it is not as painful as before but I was concerned about the swelling moving.
Sure it's nothing and it will sort itself out in a day or two.
