I was signed off for two weeks after having a gall bladder op in late August. This is a pretty standard signing off time. I'm a teacher, so wanted to get back to school for my classes from day 1, so went in at the start of term which was 4 days before my 'official' return date. I felt capable of going back. Unfortunately, I had to hold open a couple of heavy doors, move some books and desks (not carrying, just shoving gently in the right direction!) as well as stretch to switch on projectors. All quite normal and usually not a problem. However when my upper/lower back and abdomen started aching quite a bit afterwards on Friday I thought, ho hum, I've overdone it and took some pain meds. When I got out of bed yesterday it was very, very painful - cue more pain meds. Fast forward to tonight at 2am. I tried to get out of bed to go to the loo and the pain was so bad I woke hubby with my crying out in agony. I was petrified as I couldn't move! After a lot of manoeuvring involving dh holding a pillow under my back to lever me out of bed, I managed to pee, but only by standing up. I took some dihydrocodeine, but the pain got worse and worse and was now in my upper stomach area (though could have been radiating from back). Dh called NHS 24 and a nurse told me to go to the hospital 40 mins drive away. Tricky with two kids asleep in bed. Instead I opted for a GP to call me who said it is a back spasm. See your GP tomorrow. I'm thinking clearly I wrong to go back to work - but if I felt fine otherwise, how could I have known?! Has anyone else ever had this back problem and been scared of the pain?
