Deep Vein Thrombosis (DVT) Support Group
Deep-vein thrombosis, also known as deep-venous thrombosis or DVT, is the formation of a blood clot ("thrombus") in a deep vein. It can be caused by something preventing blood from circulating or clotting normally. Join the support group if you are coping with DVT and find others who are going through the same challenges.
You can ask your doc what compression he'd recommend. I think 15 is too light but I wore 30/40 compression per my doc so maybe it was just my dvt situation. I wore thigh high as well. No way I could have worn knee highs, as my clot came up around my knee and to my thigh.
My feeling is if you buy them over the counter, they may not fit just right and can cause pain.
