I have two bites (insect or spider?) that are large raised red bumps with a hard white center. One is on my side at my waist and the other inner mid thigh. Showed up small while I was at the office and over the last several hours grew to quarter sized on my leg and nickel size on my side. What bit me?
Hi, It is very difficult to tell what bit you. No matter the cause, treatment is the same. It consists in controlling the itches, swelling and any pain. For this, I will recommend that you take a anti histamine such as Ben Chat Doctor.  This would get this condition controlled. Only seek medical intervention if this fails to resolve within 24\u00a0hours. You may want to send to us pictures for review using the premium service as well. I hope this helps and I wish you well.
