Thank you for your query.
and light headedness has nothing to do with either Warfarin
or a clot. There can be some other reason for this. I suggest that you observe this phenomenon and in case it persists then it will be better if you get yourself examined by your doctor.
A clot takes some time to resolve and Warfarin is being given to prevent further clots from forming. Mixed thrombus
does not mean the number of clots. The Doppler report must have mentioned the extent of the thrombus.
I hope I have answered your query to your satisfaction.
Wishing you an early recovery.
