I'm sorry you had a tif with your hubby. It's a sinking feeling when you realize that your partner isn't 100% on your side. His reaction could very well be just that he's afraid for you. But this is so not a psychological issue - there is absolutely nothing wrong with wanting to try something that could potentially be better for you for treating pain. I'm not sure if increasing doses of painkillers is the best way to go either - just coming from personal experience. That's what I'm doing now, and it doesn't work so well all the time. You just get to a point of desperation where you want to find something that can improve on what you're already doing.
I'm with you, Rumble. Just do whatever works, and try to involve hubby in your decisions. Like I should be giving relationship advice, when I'm the mess like I am! lol
I just hope things get better, and know that we folks here "get it".
hugs and more hugs

PS I'm sorry your hubby is having health issues too, that's a double whammy to a relationship there. I hope he opts for investigation so he can treat whatever is going on.
