I was bitten by a tick about 3 months ago, there was no swelling or redness but the site still itches quite often. what should i do?

Scar tissue?: The area of the bite may have formed some scar tissue or a piece of the tick may still be in the skin and the body is trying to digest it. Take a little massage oil each day and work the area of skin gently to promote healing. Topical 1% hydrocortisone twice a day may also help. Good luck! http://www.drugs.com/cg/tick-bite-aftercare-instructions.html
