Help/diagnosis needed

Hi,

I am a healthy 28 year old male who has never previously been diagnosed with any sort of bowel diseases or had any medical issues in the past. Approximately 2 months ago I noticed a pain in my stomach for a brief amount of time when I had eaten. This passed over a few days however since this time I have been left with what I could only describe as a sensation/ dullness in my lower colon/rectum. This feeling is usually consistent however can change in severity, I do not feel any pain, have no blood in stool, BMW are fine and have not had diarrhoea or constipation. I do notice an extremely regular occurrence of trapped wind.

It's just getting me down now as I have the feeling always on my mind and as you can imagine after a few months can become unpleasant.

Any ideas/diagnosis/remedy or similar issues would greatly be appreciated
