<human>: I just took my American Bulldog for a walk, when we got to the end of the road I noticed he was walking funny but I thought maybe my eyes were playing tricks on me which tends to happen a lot when I go outside in the bright afternoon sun (Pfft, I'm a Redditor, that's normal for us computer dwellers, right?).

We continued on and after about three or four minutes he was really limping at which point I thought it'd be best to bring him home and give him a thorough looking over. I did have a quick look while we were out to check for glass but it all seemed clean. Now we're home he is in terrible pain, he can't stand on his foot, his entire leg is shaking, all the veins in his foot and leg look swollen, his leg keeps twitching and he hasn't stopped licking it in the last 20 minutes.

I have called the vets but they can't fit him in until Friday and I just feel so helpness watching him lie on the floor in pain like this. Is there anything I can give him to atleast ease the pain for now? Some sort of remedy you amazing people can offer? There are no cuts or grass seeds that can be seen. My mum thinks he possibly stood on a bee or pulled a muscle or something. Is there a sort of painkiller that can be bought from a shop or something that can be made out of human tablets maybe?

Any suggestions are really truely appriciated from both me and my lovely George.

Give me the gist of the text in a nutshell
<bot>: George has hurt his foot and is in a lot of pain. No vet appointments until Friday. Is there anything I can make or buy from the store that will ease his pain for now?
