Pain in rectal area, pressure and not fully evacuating

Visited doctors twice after stools had become smaller but no blood. Gave me an internal and said couldnt feel any lumps. Was finding when had a poop that i still felt there was more to do and pressure build up has become worse. Doctor has prescribed Fibregel to help and said probably as i am in my 60's ive not got the push i used to have and is sending me for Sigmoidoscopy which am dreading!!! Have had piles before but its not hurting when i go to toilet but cant cope with this pressure and since pushing a little too much yesterday as i felt something was still there i have been in pain since and taking paracetamol. I was paranoid that i may have the beginnings of a rectal prolapse but since reading some of this forums comments I was wondering if i may have internal haemorrhoids and thats perhaps why i am having problems going to toilet and now pain especially uncomfortable sitting. I'm thinking of paying to see a consultant as i cant wait weeks for this Sigmoidoscopy. Any thoughts would be greatly appreciated.

I’m sorry to hear you are having this issue. I can’t say much about your condition but from what I heard sigmoidoscopy are fairly less invasive than other operations so hopefully that eases your mind. I know it can be scary but you’ll get through this. Just remember this too shall pass. Best wishes!
