What is the difference between phlebitis and thrombophelbitis? I have a history of dvt (deep vein thrombosis/thromboplebitis) - had an ultrasound done earlier this week because of calf pain and pain extending into my inner thigh. The doctor said no clots, but I had phlebitis - put me on antibiotics and anti-inflamatory, and bedrest with my leg elevated for two to five days. My question is this - what caused the phlebitis? Does this mean that I had a clot that has resolved, leaving the inflammation, or does it mean that a clot was about to form due to the inflammation? I just can't seem to get a clear understanding of phlebitis without a clot present - any info is appreciated.......Thanks.....
