<human>: I can feel a lump on the more left side of my tail bone and there is pain to touch, but also after sitting a while. I have had an MRI and was told its a cyst I was born with, but I think it is more than that. I can actually feel the lump. Now I am concerned because my bowel movements are narrowed, what do you think. My doctor will not give me another MRI because they say not needed
<bot>: Hello! Thank you for the query. This lump can be a cyst indeed. However, it may be also a skin lesion which has gotten infected. For sure, it has nothing to do with bowels movements. I suggest you to consult a surgeon with this lump. IN case of doubts ultrasound is enough to diagnose it. Narrowed stools should be diagnosed as it may be a symptom of colon cancer. It is more possible if you are over the age of 50. If so, colonoscopy is necessary. Hope this will help. Regards.
