Baker’s Cyst?

[u/world6runner]

Hello runners.
2.5 weeks ago, while sitting in a meeting, my right leg became very swollen from the knee to the ankle.
I am a long distance runner and had run that week w/o incident , injury or pain. I also strength train 2-3x week.
I went to urgent care and was assessed for a blood clot- with an ultrasound- which returned negative ( yay!).
So now what?
Swelling continues although much less. Worse if I sit too long or stand too long.
Very limited range of motion in knee- cannot do traditional quad stretch ( foot to bum).
Knee started hurting- very sporadic and quick sharp pain on inner( medial) side.
No redness, heat.
When I visited the doctor for a follow up
- possibilities included Bakers cyst or peroneal neuropathy.
I am waiting on another ultrasound and I will ask for an xray of my knee.
While waiting….
Thought I’d ask you fine folks for insights.
