Don't listen to anyone, get yourself to the doctors, and get an X-ray ASAP.
I suffered severe back pains a few years ago and different people advised me to take a mixture of various drugs/painkillers, do some exercise go swimming etc etc.
Nothing worked and the pains got worse, even ended up 6 weeks in a wheelchair unable to walk or move without agonising pains.
Eventually went to my GP. Immediate treatment/X-ray etc revealed i had a broken vertebra and Osteophrosis had developed around the break which causes the spine to crack. Not got a clue how i done it, possibly the results from a motor-cycle tumble. However, i had left it too long and nothing can be done to repair it. Now too risky to touch and if they tried the results could be, i might never walk again.
I'm now permanently disabled, messed up because i never bothered to seek the proper medical advice/treatment when i first got signs of something was wrong. Instead i listened to everyone else/friends etc who thought they knew better then then the doctors.
Get yourself to your GP, before it's too late.
