Hi [@Rich03]‍ 
I wondered if you, or anyone else here, has any exprience of this and can advise.
I had a sigmoidoscopy last weekend. The endoscopist said all looked good and diagnosed haemerrhoid and skin tag. Her report said the same - diagnosis haemorrhoid and skin tag, follow-up - refer back to consultant. However, I got an appointment through 2 days later for an urgent pelvic MRI. I rang up the MRI departement to query it, they looked up the referral and said it came from a bowel consultant to get a closer look at the haemorrhoids (Which I thought was odd, as if it's only haemorrhoids, why would they need to do it urgently?) a couple of days later, a letter arrived telling me I would have an MRI scan soon due to "Rectal mass and abdominal pain" which I haven't got? I've never had any abdominal pain and I didn't realise a haemorrhoid was a rectal mass? On the letter was a phone number to the bowel support nurse, so I rang it to query. She said the referral has been made to 'check for polyps' so now I have 3 different reasons for the MRI - to look at haemorrhoids, due to a rectal mass and to look for polyps. I am so confused and worried. Could it be something sinister and the different explanations are being given to try to reassure me when really they're concerned? 
I'm 39. Felt a lump 'down there' in January and was treated for haemorrhoids but it didn't go away hence them referring me for sigmoidoscopy. No bleeding, no pain, no weightloss.
