Had chigger bites 4-days blisters wont go away.very sore?

Can take a while...: The missouri dept. Of conservation says chiggers are baby mites that can only bite through areas of thinner, tender skin. Chiggers bite to inject saliva to dissolve flesh and then eat it up. They do not suck blood nor burrow into the skin. They are are almost invisible. Hydrocortisone cream and itch-x anesthetic gel may help with symptoms. A doctor can check if bites look infected from scratching.

1 to 2 weeks to heal: Agree w dr. Kwok. Chigger bites usually heal on their own within one to two weeks. In the meantime, control itching with an over-the-counter anti-itch cream, such as Hydrocortisone cream. Consult your doctor if your skin appears infected or if the bites seem to be spreading to other parts of your body.
