I sympathise Masma, I have done my back in too today, only painful twinges at the moment but its feeling so fragile, I will have to be very careful or I will be in agony. I know all the signs, I have suffered so much with lower back pain in the past, I should not have done all that gardening in the past few days ............. Like you mentioned, I always get tummy ache too when I have a bad back, maybe it's referred pain? I'm just taking 2 Ibuprofen as I type (I know you can't) but like anne suggested a hot water bottle is really beneficial. Hope your pain soon goes and you can get away in your caravan (really wish we were going away in ours, but too many plants to put in garden!) x
