To think this is all constipation related?

[WizzardPjs]

I suffer with chronic constipation. Current situation is I havnt been for a proper poo for almost two weeks. I’ve been taking movicol but only small poos are coming out. I can feel that I’m quite severely backed up. I’ll be taking dulcolax tonight and spending the day on the shithouse tomorrow.

Anyway, past few days I’ve had pain under my ribs, at the front where the ribs meet and in the left side. Lower back pain. Bad wind and bubbling belly.

AIBU to think this pain is all constipation related and I’ll feel better after a good clear out? Don’t particularly want to bother with the Gp again

You very definitely need to speak to your GP! It’s not a bother, it’s their job. Hopefully if this is an ongoing problem your GP will refer you for further investigation but if that doesn’t happen I would suggest you ask about it.
There may be people in online groups who are medically qualified but you really should not rely on medical advice you receive in online forums.

Best of luck!

Don't be a martyr, go to the GP. You'll end up impacted if not already.
