Now we need to figure out which co-infection is causing the neuropathy and find out how to treat it (with something other than Bactrim, of course - the side effects were horrendous).
Also, Dr. Horowitz (New York Lyme expert) reports many cases of neuropathy having been resolved after the Lyme and/or co-infection(s) have been successfully treated.
So take heart! I really think that if your girlfriend can get well, her nerve pain will go away.
brucella, which is a lyme co-inf, is treated with bactrim. so that is something to look into and get tested for for sure
