Warfarin Sodium and coldness

After reading these posts I am more confused than before, because my experience is so far very different. I was diagnosed with DVT about two weeks ago and now take Coumadin daily; the Lovenox injections have been discontinued. The reason I'm so confused is I now feel the best I have in 5 (five) years.

Before being placed on the anti-coagulants I had memory and concentration issues that were progressively getting worse and greatly affecting my job, and had daily headaches. I had joint pain that made it difficult to get up after sitting for awhile; they felt constantly inflamed. I felt fatigued all the time and my muscles hurt like I had really pushed them; I just didn't have any strength, and had muscle cramps. I was constantly yawning and found my jaws hurt from clinching my teeth, subconsciously trying not to yawn. I was extremely sensitive to physical touch, even hugs hurt. I also felt extremely depressed and cried almost daily. My lips and left cheek tingled, as well as other parts of my body. Plus I would get the feeling of sudden pressure in my head (different from a headache) like it was going to pop off, and I my eyes didn't seem to track what I looking at and had difficulty in remembering or comprehending what I just read.

About 6 (six) days after starting treatment it completely changed and these symptoms are essentially gone. I have talked with my doctor and pharmacist and they are baffled. I am concerned this change, while welcomed, may indicate an underlying condition that is not yet diagnosed. Has anyone ever heard of such an impact from starting Coumadin treatment?
