I have had lower back pain (I thought it was due to my cats not giving me much room on my side of the bed) this started 4 days ago, but has really escalated today. I now realize it isn t my back but inside and it feels like it s spreading from very low back to my mid back. I have trouble sitting, laying down or standing for any length of time today. I was barely able to drive a short distance today because I was unable to turn properly. I want to add that I am extremely active, I am definitely not over-weight, and like I mentioned this just kicked in a few days ago, today being the worst. Any advice would be greatly appreciated. I plan to make a doctor appointment, but with the holidays....doc is not available. Thank you
