So I've had my fair share of knots in an injection site over the past 20 years but usually they're small and I pay no attention to them. On Mon I did my normal shot, I've been doing this cycle, eod of 2.5cc mast p and test e and everything went fine. Tues I noticed my pec was rather large and swollen so I figured maybe I hit below the muscle by accident so I would just have to deal with it. This morning it seamed a little smaller which was great but when I got home from work about an hour ago and took off my shirt I saw that it was big again but now the knot is very hard and the size of a baseball. Shit maybe even the size of a softball. Normally I think nothing of random knots but because of the size I thought I should ask some advice. The skin in slightly red but it's not anymore painful then a normal knot. So what do you guys think? Just treat it like a normal knot and let it do it's thing? At what point should I be actually worried? Appreciate any helpful advice, thanks.
