While : While there are several possibilities for this swelling, including a pilonidal cyst, perirectal abscess, or even a tumor, given that you have had a spinal cord stimulator (scs) placed in the past, should be clearly considered as part of the presentation. Complications with scs range from simple easily correctable problems to devastating paralysis, nerve injury and death. However, in a 7-year follow-up, the overall complication rate was 5-18%. The most complications include lead migration, lead breakage, and infection. Other complications include haematomas (subcutaneous or epidural), cerebrospinal fluid (CSF) leak, post dural puncture headache, discomfort at pulse generator site, seroma and transient paraplegia. I suggest that you see your neurosurgeon to evaluate this as a possible complication from the scs implant. If it is not, then evaluation by a colorectal surgeon would be the next suggestion.

It : It is hard to know without an examination. A painful infection or peri-anal abscess or painful hemorrhoid can act like this. Hard straining constipated bowel movements can make it worse. Soaking in warm bath may help. If it is an infection or abscess, you need to see a physician for treatment, antibiotics and possible surgery.
