ok ok i know the injection pain has been beat to death but i need some input

injected 1/2 ml Kapha test E in the quad thursday. the rest went in the glut as im splitting the injection sites. Quads always give me trouble.

The damn thing is still reddish, warm, swollen, hard with an indent if i push on it that slowly smooths out.

Now here is the weird part. hut like hell first two days not now just a little tender, no fever, feel fine, walk fine BUt the thigh and now the area above the knee is clearly swollen.

Abscess? Infection? are my nerves just getting to me? it has been 5 days now and it hasnt really gone down much ( the swelling) it is about 3-3 1/2 inches across. Not an angry red but warn to the touch and pinkish.

Could I have made this worse trying to massage the swelling away?
