1st cycle Test e/Dbol

[BozBoz]

This is my first cycle log so pardon me if I get things a little wrong. I started this cycle with dbol only until my gbn packages started arriving and so am now on both test e and dbol. Have been training on/off for 8years but solid for last 3. Good diet and lucky me got a constant supply of good food at work! Looking to bulk with what I researched to be a classic combo. My first cycle was anavar for a few weeks with little gains from that.

So far on this cycle:
10mg/day dbol week 1
20mg/day dbol weeks 2 & 3
30mg/day dbol + 500mg test e(mon/thur) week 4

Have had my third shot of test e yesterday back to my right quad again and that's all fine, not too sore.
My second injection last week on Thursday was not so good. Went in okay and injected slowly, however when withdrawing needle got blood straight away. So was sore that day but could walk/squat normal so on Friday did my legs. Big mistake I think. Since Friday my knee and left side of quad near my knee has swollen, now the outside of my calf. Cannot walk without limping, have tried to rest it but have been at work since it happened so not much chance. I followed all the sterile procedures for self injecting (as far as I'm aware). No fever, no lump under injection site just really swollen. Any ideas?
Was thinking I might have a knee injury but I wasn't squatting that low at the time 'just in case' I aggravated the injection site and the knee itself is not painful to touch, just sensitive around the swollen areas.
My next shot is on Thursday so not sure if it would be best to go back to my right quad again or try my delt?
Any ideas/suggestions would be great thanks
