Break that down into two things. Makes it more reasonable to look at.
1) 150 miles, assuming you have mostly highway speeds, is about 2 hours. I had to drive about 90 minutes, years back, to find the right person to diagnose and ultimately fix my jaw problem. Fun, no, doable, yes. I would have driven lots further if necessary. In fact, at first, thought I was going to have to drive to Chicago (3+ hrs) or Mayo (4+).
2) What is your wife objecting to? Why? Is she fearful of it causing more issues? The unknown? Financial implications? It seems to me she at least needs to understand how miserable you are and at least be open to exploring all options out there. You deserve to get validated opinions from experts.
