It’s much better. Though, I’ll say I did never go to a doctor so I can’t say for sure what it was. I took 4 days off iced, stretched and really tried to stay off of it. I also switched running shoes. I have always run in the same model of Saucony Libertys so I switched over to the Rides which have more cushion and rotate with Altra Escalates. If I squeeze my foot in that spot I can still feel it but the pain isn’t nearly as bad as it was.
I also was using these, which I really liked SB SOX Compression Foot Sleeves... https://www.amazon.com/dp/B01MFEBO3V?ref=ppx_pop_mob_ap_share
Not sure if they helped, but it felt like they did.
Honestly you really just need to put in the time and effort. Exercise and stretch every day or as often as you possibly can, and do not overwork it. I don't know where you're at in your recovery but here's just some general advice.
Firstly, these are more "optional" but every little thing will help: I bought some compression socks and I wore them every day especially if I was going to be walking. This will keep your arch supported. Pair them with some cushiony insoles and your a lot of load off your plantar fascia. Next, look into taking vitamins. I found this website to help guide me, but I ended up just taking a multi vitamin every morning and extra magnesium and tumeric here and there.
Next up: Stretching. Stretch your toes, and all your calf muscles every day, multiple times a day. Stretch your calves on every surface you can: curbs, steps, against a wall, in the shower, etc... whenever you're just standing around waiting or doing nothing try to stretch your calves. Stretch both the Gastrocnemius and the Soleus muscles. There's tons of videos/articles on these, so just do some research and stretch daily.
Finally Exercise: I would typically do a handful of exercises every time I went to the gym since I was already in the zone (2-5 times a week) but there's also plenty of stuff you can do at home even while sitting down. You'll need to strengthen all your foot/ankle/calf/hip/glute muscles in order to take more load off your fascia and just overall speed up recovery. You can't recover if your fascia is still taking the majority of the load. Again, there's tons of info online if you do a little research. Your end goal is to be able to do "high load" foot/ankle/calf exercises without any pain during or after. this video is a good one for more "beginner/intro" exercises but really there's a bunch of exercises you can do to build ankle mobility, foot arch strengthening, and just overall dexterity. Here is another video I found useful to help me identify what I needed to work on.
For examples of high load exercises that you'd want to work up to, I bookmarked this instagram post by the Prehab guys (big fan of these guys). These are going to put a ton of strain on your fascia so chances are you'll need to work up to them (it took me months to build up strength to even feel comfortable doing a couple of these at a time, but maybe incorporate one or two into your routine after a few weeks of rehabbing and see how it goes.)
I know this was a long response, but generally speaking you want to always be working on something. If you're sitting down, practice spreading your toes or flexing your arch. Stretch and massage often unless there's pain. Take it slow, learn as much as you can, and be conscious of your foot.
Running is my outlet. I go crazy without it - have been running since I was 13 (now 33). It sounds like it is your outlet too.
Some things that may help: Commit to an off day for yourself at least once a week, purposely schedule in slower runs (on these I "screw up" my first mile so I can't get a "good" time anyway, or I leave my phone home altogether so I can't track my pace), accept that failure is a fact of life (and not running is NOT failure, life is all about tradeoffs and sometimes you need to prioritize other things. Running will always be there for you.).
Re plantar fasciitis, these two SOX products have helped me more than anything else out there (sometimes I even double layer them). Also, foot massage your arches with spiky massage balls.
