Stomach Issues can't get doctor appointment

Hello all

I have some concerns about my stomach. I can't see a doctor for another 5 weeks.

I developed a bloated stomach which was tender about 2-3 weeks ago.  it came from nowhere, as I had been ok.

Over the last 2 weeks I have tried to manage the issue  by reducing food and types of food etc,  and was advised by pharmacist to take buscopan(IBS treatment), which has reduced the swelling and the pain but not removed it. I have quite a lot of wind and my stomach gurgles a lot especially when I lie down.

no blood in bowel movements,  which are generally ok, I'm always a little constipated .No vomiting or temperature

I am unclear if my symptoms point towards cancer, IBS Ulcer or summering else.

not being able to get any advice is quite concerning

thanks for any help
