if you can't afford Tafamidis, you could probably get away with taking
- Flufenamic acid
- Valtoren (Diclofenac)
- Diflunisal
off-label.

IANAD but I believe that Valtoren has the least side effects, but in general since they're all NSAIDs they have been tested for long-term analgesic use, so they're relatively safe and quite inexpensive.
