Dvt in left calf diagnosed a week ago. on lovenox (2x day) and 5mg coumadin (warfarin). experiencing left sided tingling in leg, arm and head (slight headache too). is this a side affect from meds?

See a doctor: The tingling on one side of your body and headache has me concerned about a bleed or clot in the brain. Please go to the emergency department at the hospital to get checked out.

Blood thinners: Headaches are not a usual side effect of Coumadin (warfarin). If this is a new headache or a variation of the usual headaches then seek medical attention to make sure there is no bleeding in the brain. The risk of bleeding is low (1.5%) but headaches are a concern that needs medical attention.
