I had mine done (one leg) from next to my spuds to my ankle and some vein re routing Etc.
Should have done it years ago, ached when riding and always had back problems because I stood with my weight on one leg mainly to stop the ache and threw my back out.
4 weeks off work no major pain, riding after 3 weeks, leg now doesn’t look like a road map of the mountains of Scotland
If it’s causing you pain get them cut out.
