Hey Jag, whine away, good grief as much as you have been whittled on honey-no wonder you have left over pain from Haitis. My knees have been whittled on alot too, well one of them 4 surgeries on the left and one on the right. Your body is your best weather forecaster as you know. I like you try to remain as active as possible, we have to or we are cooked louie's.
I had R/F done on both neck and my low back. Facets problems at L5-S1. Prior to having this done my pm dr did diagnostic blocks in his office to see if I would be a candidate for the R/F. I must have passed I had them done. I did great on the cervical and about medium on the lumbar. Pain was back in 6 months on the back but that is not unusual per my dr. He gave odds of relief for 6 to 12 months. Just putting a bandaide on things. Keep in mind your ins has to approve this stuff too. I was glad I had it done.
I think Frances answered your questions about the meds. I hope you get to feeling better, but lets face it, winter and cool weather is not our friends. Hugs coming your way.
