When I touch my chin to my chest, I get an aggravating lower back pain.  Ive had it for 4 days total now with little to no improvement.  I am 61 male 165 lbs. age 27.  I do a ton of weight lifting.  Is this a muscle strain or something more serious?
Probably your back pain is mechanical due to lifting weighs.is this increasing on coughing or sneezing which suggests articular pain due to disc prolapse.don't worry .take absolute bed rest for 1 week n take analgesic with muscle relaxant like tab flexion Mr(diclofenac n chlorzoxozone) .if no relief after 1 week pls consult neurosurgeon.
