A blood clot in your leg, also known as a DVT (deep vein thrombosis) can be a very serious diagnosis if not treated properly. I would be curious to know if this particular MD did any diagnostic tests to accurately diagnose this such as a lower extremity ultrasound or at least measure the diameter of both of your legs and compare them. Often times, if there is a DVT there is a difference in the diameter of your calf (the most common place for a DVT to form). Another (less accurate) indicator is pain when you flex and extend your foot. I have never heard of the medication that he prescribed for you so I do not know much about it. What I do know is that if he highly suspects a DVT you should at the minimum have a lower extremity ultrasound done to confirm the diagnosis. Once it is confirmed, medications such as coumadin (which is a blood thinner) is relatively inexpensive and you may only have to take it for a short amount of time. This is a pretty serious medication in itself and should not be taken without a definate diagnosis. If I were you, I would seek a second opinion before taking the medication prescribed, that way you would have confirmation one way or another regarding the potential of having a DVT. Also, never be embarassed that you are unable to afford medications! Tell your pharmacist and the prescribing doctor that your funds are tight..often times they have less expensive alternatives or generic medications that they can prescribe or substitute for you. Good luck!
