having had several DVTS I can speak from experience...I am a thrombofeliac.
Its no fun to have a DVT, THEY HURT LIKE HELL...feels like your leg is gonna blow off from back pressure....wicked pain.
The DVT and the extremety is a local and regional CI for three months and you need a MD's approval after that time.
The clot is not dissolved by blood thinners, only by Heprin which you only get for two weeks, via stomach injections....I do those my self when I had the last DVT.
So the clot may be there as a partial blockage for the rest of the patients life like the one in my left common femoral...that means it will aways be a local caution.
The therapist needs to indentify and treat S/S of course. The pain is due to the back pressure in the vein, something we cannot help with other then good advice like elevation, rest, stockings, follow MD orders and medications pre three months DVT...and getting a balance on their INR with blood thinners is often a crazy balancing act.
I know that my leg pain was most helped with the injectable Heprin and with also anti inflammatories as the inflammation is triggering the nocireceptors like crazy, so we need to drain the leg, decrease the stretch receptors overload with elevation, stockings, that pump which is not dangerous if MD advised.
After three months we can approach the leg with Lymphatic drainage and John Barnes Myofasacial Release techniqe, also Active Isolated Stretching.
Usually you end up with Post Thrombotic Syndrome due to valve damage post DVT back pressure which occurs by the third day....why they don't take those suckers out I am not sure, in Europe they do...but here they do not so you are left with constant backpressure with damage valves and you need stockings for life. Make sure they get prescribed stockings BEFORE Post Thrombotic Syndrome starts.
