So the pain hasn't subsided even when you sit and apply no pressure. Hmm... That's odd. There's definitely something irritating your nerves, because ultimately that's what registers pain. Check to see if its inflamed -- if it is, then most likely an infection. Also check to see if you accidentally punctured your skin -- might be a splinter or something alike. Generally, pain comes in response to injury, so you've most likely injured your foot without knowing how.
I actualy asked this question as part of a wider concern I have at the moment which is that I have some form of central sensitisation. I will copy paste the explanation of my situation:
18, male, had anxiety for ages but only been real bad over last 2 years. Mainly health anxiety.
From 5 to 2 months ago (i.e. a 3 month period ending 2 months ago), had psychosomatic wrist pain brought about by stressing about potential future issues.
From 2 months ago to 2 weeks ago, only once had a wee bit of wrist pain which was when I was trying to do some push ups.
In this time (from 2 months to 2 weeks ago), I was stressed about other aspects of my health, some of which lead to psychosomatic symptoms and some of which didn't.
2 Weeks ago noticed that if I type continually without a single break for 2 minutes, I get tightness and pain in right wrist. No pain when gaming. Continued to use PC for about 10 days, never had any pain when doing this. Over last 4 days have been trying to make sure I don't have pain. Sat in a weird position 2 days ago which made my shoulder hurt. Next day woke up and shoulder was sore, no idea if this is because of the weird sitting position, as the pain went away after I moved, so I don't know why it would appear again next day. Around this time also experienced the first weird raynauds pain in right foot
1 day later (yesterday) I read about central and peripheral sensitisation. Now I have pain on right side that seems to move around constantly, but never in more than one place at once (plus if I pinch myself or induce pain any other way, it stops the other pain).
And if I look back over the last few days, I feel like I can find example of stuff that was a little bit too painful, but that could easily be me stressing about stuff and it's normal.
Over the last few days have been experiencing the raynauds thing more, could be because of the tablets I have started taking, however have no idea why it's in one side still
Now this worries me in 2 ways:
1) That I was already sensitive to this because of my anxiety, maybe HPA imbalance, idk if that would happen I read about that somewhere. I don't have panic disorder or anything, just bad GAD and health anxiety. And that this combined with the potential minor RSI in my hand (and not stoping working even after I noticed it (although never had pain when working)) caused some kindof quick onset central sensitisation.
and 2) That the pain I got when trying to do a push up about a month ago, was as a result of some kindof sensitisation from when I had 3 months of psychosomatic pain, and that this could get worse in the future (going into comp sci so gonna be using a computer a lot).
All of this pain is on the right side, other than a few rare occasions, or pain that is in the middle (back pain, and had eye pain, both eyes).
The thing that concerns me about this is that I don't know how the pain from the cold could be a psycosymatic, "because I'm worried about it", kindof thing, as the first time it happened, I wasn't yet worried about Central sensitisation, and was only worried about my wrist.
I don't know if it could possibly have happened because I was worried about my right wrist and arm, which meant I was more prone to pain on the right side in general or something.
This is the only aspect I can't really explain other than that I do have central sensitisation, and it is mainly on one side.
As a lot of other things don't make sense in regard to it being central sensitisation, namely the lack of significant pain leading up to this, and the fact it hasn't got worse over the last week, despite appearing with a couple of days.
The reason I asked the question on here only referencing the raynauds thing was because I was hoping to find an explanation that could explain it so that I could disregard it as a potential factor for this.
Basicaly I don't really know if I actually have some central sensitisation or whether all of this is just because I am worried about it.
