painful lump at injection site?

[stickyfingers]

ive been injecting my quads for a while and i seem to have developed a a little lump at one of the injection sites. i thought nothing of it at first and didnt really notice it as it didnt cause me any pain and figured it would go away. ive now had it for maybe 3 weeks and its starting to cause me a bit of pain when i put pressure on it. the lump is very small and about the size of a coin (10p coin in UK). it is also a bit red. does not feel warm though.
could this be infection? bruise?

i had the same issue with glute not too long ago it was a lump and it hurt like a muther fcker and it was red but 2 weeks it got better and now fine 3 weeks sounds like a long time if it hasnt gotten better by now i think maybe you should go see your doc now it shouldnt be getting worse if so doc asap man

HAHA its pretty common sense if its getting worse rather than better pretty clear to go to the doctor.

If it's red, hurts and warm then most likely it's an infection and you need to see a doctor to get antibiotics unless they are OTC there like many places.
