<human>: Hello I take warfarin for a blood clot, My fingers and hands get red and the palms show redness my finger tips and nails are blood red. my left hand is minimally numb. After 4 to 5 weeks on warfarin my  left leg and foot is still swollen. I have some pain in my legs. What is the reason for this and how do I defeat it. thank you
<bot>: HIT hank for asking to ChatDoctorI really appreciate your concern, the symptoms that you have discussed here may not be due to the warfarin this seems hypersensitive reaction I would advise you to wait for some days this will go away, if it does not subside then I would suggest the following treatment1) Tab Levocetrizine 10 mg there times in day hope this information helps you, take care and have nice day.
