Missed an injection is it ok?

This past weekend i was in Laconia for bike weekend and i missed my inj on sat. the last time i injected was last thursday AND IM injecting tonight instead of sat like i had planned. i know its not good but will i be fine as long as it dont happen again? ALSO, some shit happened up wthere and my ankle is all ****ed up so i cant work legs for a few weeks...i should be fine just hittin upper body for now right? my ankle is like the size of a soft ball right now, thats why im not working it until the sprain goes away.

shit wrong forum sorry guys.
