<s>[INST] Hi Dr, I have been having this sharp piercing pain around my lower abdomen just close to my navel, which seems to radiate down to d point around my genital. This comes and goes away but can be felt when ever I sit down and sometimes when I stand. The confusion is I had an appendicetomy when I was barely 17 yes and 17yrs later I begin to have these pains. What could possibly be wrong with me? [/INST] Hi Thanks for asking Chat Doctor. What ever symptoms you have written may not be related to your previous operation. But you should get your ultrasound done to confirm the diagnosis. Though till then you should take plenty of oral fluids' fiber rich small and frequent fiber rich diet. You can take antacids SOS and add mild laxatives if constipated. Consult your doctor with reports if not benefited. </s>
