Is having a tick bite on your skin for an extended time a sign of possible lyme disease? I've felt Terrible for a while now and had nerve issues in my feet and legs, cognitive/short term memory issues, back pain, itching, joint aches, extreme fatigue. I've had a standard urinalysis and cbc done with no issues. I've been bitten by 4 ticks this season and the site where I removed one of them is still red after 6-7 weeks.
Could that still being there be a sign of Lyme?
