Can a high inr (5.8) cause my feet to go numb while sitting? i take coumadin (warfarin) daily for a clotting disorder.

If the high: Inr was going to cause numbness i would expect it to occur whether sitting or standing. Otherwise, i would blame the numbness on a nerve impingement when sitting. Irrespective of the fact you take the coumadin).

Inr: As stated it would occur standing or sitting if the inr had anything to do with it. See your neurologist for assistance.
