Check your health system’s coverage, and try physiotherapy, before pricing this abroad
Before comparing international prices, it is worth establishing two things. First, whether your own health system would fund perineoplasty, since a perineum torn during delivery or an episiotomy that healed into a tethered, painful scar is a real injury with an established reconstructive rationale, not a cosmetic one, and this is sometimes funded through a referral pathway.
Second, whether pelvic floor physiotherapy and manual scar therapy, taught by a pelvic health physiotherapist, would resolve your specific problem without surgery at all. This genuinely resolves a substantial proportion of perineal scar pain, takes months of consistent work, and is the reason some women who complete a proper programme find they no longer want the surgery at the end of it. Both of these are worth pursuing seriously before any private or international price becomes relevant.
