painful lump at injection site?
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?
