Insect bites and stings will usually cause a red, swollen lump to develop on the skin. This may be painful and in some cases can be very itchy. The symptoms will normally improve within a few hours or days, although sometimes they can last a little longer.
Why do you get a lump when you get bitten?
Your immune system makes antibodies and releases chemicals to protect you. That causes the initial swelling. Then, special immune cells collect around the site of the bite. That makes the lump get hard.
How do you make a bug bite bump go down?
using an ice pack to reduce swelling and pain. taking a cool bath without soap. applying an over-the-counter (OTC) hydrocortisone cream or calamine lotion for swelling and itchiness.
What does it mean when a bug bite turns hard?
Infection might occur at the site of a bite, causing redness, warmth, and a hardening of the skin around the area, with pus draining from the wound. Scratching the wound can also lead to infection and leathery, thick skin. This process is called “lichenification.”
