I have been suffering from what the doctors are calling musculo skeletal pain for 3 yrs now. It only comes on in the night, the pain is in my back on the left side just under my rib. when the pain first starts its quite weak but gradually builds up to a point i feel like im being rung out like a towel. I have been prescribed strong pain killers but nothing eases it. It can last from between 2 and 5 hours. Can anyone help with any pain strategies or is anyone suffering the same?
