I have red bumps on my lower legs, lots of them, this is the 4th time in 8 months I have gotten them. They do not itch but hurt to the touch, are red like pimples and are just in the front of my lower legs. They all seems to happen with 24 hours after I shave. I use new razors and shaving cream but I am not sure if I am coming in contact after with something or I am just breaking out in razor burn? I thought they maybe bug bites but they do not itch and no one else in my family gets them. I have a photo if that will help. They tend to last a week (fading slowly every day). No other symptoms, no fever or anything. Please help. Thank you!
