Hi, I had 4 bites on the upper part of my legs they all were infected they were about the size of a mosquito bite but they looked infected. Each bump had a straight line straight across from the bump. I went to the doctor thinking it was a spider bite she gave me a presp. For antibonics the bumps have they had a line across them all feel like a scab has came up on all of them it has been 2 weeks now no more infection but I still have the scabs all the way across the red line and bumps.
