4 days post IPL laser hair removal. Dark spots, bumps, itching and swelling. (Photos)

When can I expect improvement. Using Vanicream HC, cold compresses, and got a steroid shot today. I’m just getting “it’s fine” from where it was done, but I just don’t buy it. They told me in 3 days everything would be better. Day 3 & 4 have been the worst. I wake up with massive swelling each morning! Please tell me this will soon resolve with simple remedies.
