After getting an insect bite yesterday morning.
The "bite" is roughly 1cm diameter and a deep purple/red colour. It's sore but it doesn't itch.
I've run on it this morning and it didn't bother me other than a bit of stiffness while I was running, but now my whole ankle and about 1/4 of the way up my shin/calf is very swollen with a slight yellow tinge.
Do I need to "do" anything or just rest it for a bit and see what happens?
