@shamnelo I'm glad you had the Doppler test as my first thought was a blood clot. You may want to look for a massage therapist for a lymphatic message if they think this is lymphedema. Also myofascial release may be beneficial because it can stretch out tight scar tissue and perhaps that is yanking on a blood vessel and altering flow. If your muscles are very tight, MFR may help that too.

Here is our discussion where you can learn more.

There is a provider search here. Massage therapists also may be certified for MFR, so you may find both in one provider.
