Hi, It sounds like it might be an old infection. I would suggest you find a LLMD ASAP and check it out further. 3 weeks of abx are not enough. Others here can help you find a LLMD. Just post. Just a hint you should put a topic line in your post you will get more responses that way.
2001 symptoms started:
Tingling in fingers and toes both sides, not tested at that time for LD
2007 Summer tested pos. WB, diagnosed with LD, tested neg for co-infections thru Igenex
Abx - Doxy 100mg 2x/day for 3 weeks (before diagnosis)
Amoxicillin 1gm 2x/day for 1 month
Amoxicillin 1gm 3x/day with Probenecid 500mg 2x/day 5 months
Currently on Dr. Zhang's protocol
