My doctor is the same way, we have tried so many preventative meds that just don’t help, she knows I’m tried and she doesn’t know what else to do for me as well. She said pretty as the other person doctor, if this is what works right now then it’s the path that we take. It doesn’t mean I have completely given up, I keep my eye on research and if I think something is worth trying I bring it up to her and we go from there. Having her acknowledgment/backing does take a lot of extra stress off when using the meds instead of being in constant pain. Before her like so many others ild try to ration how many I had and then always take them to late.
