I have started having a vibrating sensation in the rectal

Patient: I have started having a vibrating sensation in the rectal area. It comes every 10-15 min & only lasts a few seconds. Its very similar to the feeling of having a cell phone in your pocket receiving a call on vibtrate, it’s not accompanied by any pain. I do have a spinal injury in L5 & S1 & was diagnosed also with polyps in my colon a few years ago. I’m concerned this may be a system of something serious but I’m in a very dire financial situation & am unable to see a specialist.
