Hi. I truly believe that weather has a huge impact. I have everyday pain but when I was in Fl from the humidity I was so swollen and was back to taking vicodin after like 6 months of none. I could barely put my foot down from pain. A fluke maybe. I am in Mi right now and yesterday was warm and sunny. I had a better day. Today is cold and rainy and I hurt so much. Another fluke maybe. To me though there is too many connections. I am sorry your car got hit but thank goodness you are ok. Getting hit by a patio table could be deadly. Hugs and feel better
