Is it ok to sit with your legs crossed 10 days post TT?

Hello Thank you for your question. It is best to follow the post op instructions of your board certified plastic surgeon. As every Plastic Surgeon has different instructions. Best regards

Doubt it would cause a problem, but if you are stationary for too long, blood clots could develop. Always good to keep moving and cross at the ankles. Best wishes. 

While I doubt crossing your legs will impact your scar to any significant degree. Crossing your legs too much early post-op may contribute to venous stasis and risk of clots. Best to review with your surgeon.
