Thanks to @Fumduck for suggesting that this might be gout and providing some reading materials for me. I read through those and some others and decided I would try and treat it myself before going in for an x-ray. The treatment I found had 6 things to try: 1. Celery seed extract (or celery juice) 2. Black cherry juice 3. Stinging nettle tea 4. Fish oil 5. Bromelyn 6. Magnesium I have a bunch of celery and cod liver oil, so I downed some cod liver oil and have been munching on celery all day and drinking a ton of alkaline water. It went from not being able to put any weight on it when I woke up this morning to I can stand on the sore foot right now and walk around. Gout is usually caused by a shitty diet loaded in sugar and carbs, which is not me. It can also be caused by not drinking enough water because your body wants to piss it out, and when it can't due to not enough water, it accumulates in joints, most notably the big toe, then crystals form and it causes pain. That is me. I was avoiding the water because I didn't like having to piss all the time, but pissing a dozen times a day is way less of an inconvenience than not being able to stand on your own foot, or going through a bunch of pain to put on your socks and shoes. So there it is. Drink good water often so you don't have to go through needless pain.
