Old tick bite site inflamed and itchy

Patient: I have had a couple of tick bites over the last few years. Two of the ticks had to be pulled off. Prior to these two bites I was diagnosed and treated for Lyme disease. Both of those last bite sites will periodically inflame and itch. What can be a reason and can anything be done about it?
