Over a week ago I started having this lower back pain that bothers me while sitting, standing, or laying down. Its the worst while laying down, I can't sleep I keep tossing and turning all night. I also noticed I can't stretch my hamstrings anymore, I used to be able to bend over and touch the ground I can barely get past my knees now. I have been doing lots of cardio and leg work more then before. Can it be my hamstrings got so tight they are causing this?

I feel a similar weird pain in my hamstrings especially the left one. That's whats leading me to make this connection. Anybody ever have this happen? Or know anything about this, I literally can't sleep as I type this ???
