I saw the PA. She looked at it and said let's get an MRI. So, next week I'm expecting to get an MRI scheduled.
And to Wolfhaley's point, yeah, I'm dealing with a variety of issues. I've not been really good about taking care of my body over the years. It's one reason why I haven't pushed my kids to get involved in competitive sports--particularly contact sports or sports that include potential high impact.
In the COVID thread I had mentioned an issue I've been dealing with that I believe is related to the flu vax. It's called Guillain-Barré Syndrome (or GBS).

It's rare, but can be associated with the flu vax. I got the flu shot prior to my business trip to Puerto Rico in October. Truth is I don't recall for sure whether the numbness started before the vax or not. But it was around the same time. She's going to give me a referral to a nerve specialist where they do a nerve conduction test.
As far as plantar fasciitis goes, I've dealt with that in the past as well. The first time it happened I was in college and wore and old pair of cleats playing flag football. Haven't had a lot of issue with it since then. I do generally choose my footwear to provide arch support due to that experience.
I know that Joe Rogaine is a minimalist shoe guy. I've looked in to it some. I'm not sold on it. OTOH, for this tendon issue, I have wondered if the hiking boots I wear to play DG are actually a cause for this issue. They are high top style, and have a pretty stiff support. So, they could be pinching the tendon.
Thanks for the feedback--sometimes I need someone to point out I'm being dumb not getting something looked at. I should know better. I tore ligaments in my shoulder in 2003 in a motorcycle crash and waited months before going to a doctor and ultimately getting it surgically repaired. I've even given that advice--to go get stuff looked at sooner rather than later. Thanks again all.
