Glad you found this community, and welcome to a small, exclusive group you never wanted to join. Take a deep breath, hope for the best, and realize that each person's experience may be a bit different. The great majority of us have come through and are much better. Improvement takes a long time, and sometimes things get worse before real improvement sets in. My bat bites were in the back and palm of my right hand, the tingling and burning began in the palms of both hands, and eventually the feet, it all has to do with the nerves being affected not so much by the bite as by the vaccine. I can't address your titer questions as I never had a titer done. Hopefully other veteran posters are still checking in and will contribute. The anxiety can be horrendous, and I think some of it is a natural response to a truly frightening situation, and some of it is neurological caused by the vaccine. Hope it doesn't get too bad for you. For me it was like riding out a hurricane in a rowboat, but that storm has passed. I'm now 15 months out and doing well. At this point I'd call it tiny setbacks and large improvements. I'm much stronger, less fatigued, and have only tiny little reminders of this whole experience when I really push myself very, very hard physically. Hang in there, and hopefully the course this runs with you will be mild. We're here for you.
