New and old symptoms

I am struggling with doubt and just making heads or tales of what is happening. I have been running for two weeks and yesterday had a big flair in knee pain (bilateral) and more acutely at a surgery site in my right knee (feb. 2021) after 1.5 weeks of no pain. Then my right forearm is tightening up, like it used to, and I am having odd thumb and finger sensations, new, that make touch sensation seem muted and an old shoulder blade pain has started to ache a little. Now after 10 minutes of yoga, my left elbow is screaming, this is where I broke it in July 2020, and I haven’t had any pain in it since February 2021….what is going on? I am trying to force myself to start an upper body workout to coincide with my running, but I feel like quitting running altogether as things seem to be getting worse.

Thoughts? Help? Advice?
