<s>[INST] Hi there,For just over a week I've had a bloated gassy feeling in my lower left abdomen and a dull 'naggy' feeling in my left testicle. I've examined my testicles and felt nothing out of the ordinary. None of the symptoms are consistent, they seem to come and go. I'm also slightly constipated.I'm going to see my GP as soon as possible, but wondered if you were able to shed any light?!Thanks [/INST] HelloThe bloated gassy feeling with pain in the left testicle may be due to ,1 Left renal colic , diagnosis can be confirmed by ultrasound of left kidney . As you  mentioned that there is pain also in testicle so more chance of stone in left kidney.2 Amoebic colitis may be the next reason , so get in stool examination for entamoeba histolica.In this type of cases usually colon is palpable so physical examination by  a physician is very important .3 Epididmo-orchitis is an important cause of such pain and gassy feelings , so physical examination by a surgeon is very important .In my opinion deal as mentioned above. Good luck.Dr. HET </s>
