Im having severe back pain.  My back is swollen and bruised around my spine on my lower back.  I went to some military training and had to do some stretches and things to check flexibility.  I had to do one something like a push up but with my hands above my head.  When I pushed up my back made a lot of popping and cracking noises really loud.  What could this be?
Hi, From history it seems that due to severe stretching exercises during military training, your all muscles of back and abdomen got heavy strain leading to severe muscle spas. Take NSAID like Diclofenac with paracetamol with muscle relaxant medicine clock wise for 3-5 days. Apply hot fomentation on the part. Apply analgesic, muscle relaxant cream locally. Give rest to the part for 2-3 days. Ok and take care.
