Hi, I have been to my doctors 5 times in as may weeks with what I thought was Sciatica, however one doctor diagnosed it and another said lumbago, it is now diagnosed as back pain, ive been given pain killers over and over however the pain is so intense and to give you an idea I was a passenger in a car yesterday and we went over a bump and it felt like a wide knife came up through the seat into my left buttock and I just cried out in so much pain, it also stops me from moving when I get up from a chair, mornings are just as bad, I lay in the bath and it feels like a lump is there and is very sore.
