Did a pec injection a couple of days ago. Put in 1 cc of Fina w/ a 25 ga. 1" pin. Went in nice, no pain. No bruising for the first two days, but on third day, noticed a small dark spot. It feels a little hard underneath, but no pain. None when I touch it or flex the muscle. Used the same Fina in other injections with no prob, so I know it's clean. I'm just a little freaked. Any docs or bros that had similar experiences, iI'd really appreciate a response to put my mind at ease. Thanx.
