Hi munchie!

Exercise after DVT diagnosis has not proven to be so effective as expected to! Although exercise increases blood flow, it is questionable whether venous blood flow (particularly deep venous) is improved when DVT is present. I would suggest to 'test and try'. That is very mild exercise and watch for symptoms. If 10 minutes of bike or walking causes light pain and swelling, then do not increase time or intensity unless you have no such symptoms. Keep on with medication and perform mild exercise until symptoms disappear.

As for your knee rehab exercises, since the knee is part of the lower extremity, it is almost certain that any exercise could aggravate symptoms. Therefore, try mild exercise, such as leg raises in supine or prone and definitely without resistance.

Looking forward to hearing from you. Unfortunately, research data is poor concerning exercise and DVT. So, be gentle with whatever you do!
