Hi there ~
As long as your wife is under treatment for the stroke
and is on medications and is under the care of rehabilitation
doctors, I do not see any necessity for further treatment. In fact, she is getting the best care that I can see from what you have written, unless you are missing something. I would not give the clot like appearance on her groin too much attention, however I would have you bring it to the notice of the rehabilitation doctor. I wish you the very best in your wife's recovery.
I hope this helped. Take care and have a lovely day !
