A Tarlov cyst at S2 should not cause leg pain as the S2 nerve radiates to the perineal region (coccyx region) and does not radiate down the leg. I would make sure the symptoms are originating from the Tarlov cyst before further discussions are made. Local Tarlov cyst pain can occur by bone erosion but there has to be significant erosion as I’ve seen 50% of the sacrum eroded without symptoms.
