I have been suffering with really bad abdominal pains for over four weeks now in the lower right hand part of my abdomen and also feel extreme pain right through to my back which is always present but worse at night. The pain is so bad that I have difficulty in straightening up and moving - sometimes its a burning sensation and sometimes its a gut wrenching stabbing feeling. I have had an ultrasound and blood and water tests which found nothing but I am in agony  - my doctor just says if it gets worse go and sit in A & E - which I already did in the beginning and they said my doctor would need to diagnose the problem. Can anyone please point me in the right direction - I am frightened what it could be?
