susy75 - I don't want to scare you but will share my cautionary tale!
I am terrified of hospitals and needles, hence ignoring symptoms (didn't have a clue what they were from) for 4 years. Never went near the doctor. Until, one day things were so bad I was literally knocked off my feet, told my husband I thought I was dying and still tried to stop him calling the doctor.
During that time I had lost 2 1/2 stone. Taken off to hospital, diagnosed with gallbladder but, it was also filled with puss and had somehow distended to my lower right abdomen where it had fused itself to my intestines. The doctor said gall bladder trouble should never be ignored it can be life threatening especially if an infected one bursts.
Spent five weeks on antibiotics because they didn't dare touch it in that condition. Eventually had it removed by keyhole, took a lot longer than they expected so, they took a chance and didn't flush the billiary duct. Two weeks later, I am back in hospital with pancreaitis, three stones were found stuck in the billiary duct. I was really ill.
Now that's sorted, I am still left with stomach problems caused by all the trauma.
So please don't try to ignore it, it will only get worse. Oh, and from this absolute coward, the keyhold surgery was probably the least traumatic thing of all, a piece of cake :)
