Once you are totally bed bound, the risk of DVT increases, and I couldn't remember how many here had experienced them, thanks Nikki!
Even if you are getting up with a hoist and into a chair and being toileted etc it makes a huge difference.
Ardalon can someone do some passive leg exercises on you daily, twice daily would be best? But taking medication may also be wise, I'm sure your doctor is looking at the complete picture.
