Suggest Treatment For Pain And Swelling In Foot

Hi my name is Charlotte my age is 38, I'm 5 5 in height, amd weigh about 160. (my leg is prob 20pds) It started with swelling of my ankle, doc sent me to a foot specialist and send me to have 6 weeks of PT. Said I had foor tendenitis. This all started in Feb this year. After my PT I had seen tha my leg was now getting swellen. Went back to my doc and he done an ultra sound and said I had DVT. He send me to ER and they did nothing at all. They sent me home to take take some kinda of shots and put me on coumidin. I take PT levels at about a 3. Now a month goes by, my leg is bigger.now doc sends me to get a CT scan and that showed the clot in my groin. I have been wearing compression stocking this whole time. It's now mid May and my leh is hot, red, I run a low fever only at night and my leg hurts to touch. My question to you is what can I do to stop this pain and swelling?? Please help..
