I started my first cycle of sust about a month ago and am experiencing the same side effects, in additon to chills, night sweats and flu like symptoms. My injections sites usually stay painfull for about a week and I also have a knot at the injection site. I took the advice of someone else on the Board and started to cut the sust with .5 cc of bold/EQ and injected into the delt. The first inject into my delt was sore for a while but I did not get a knot. The second shot into the delt I did not experience "any" pain or other side effect. Some say that it takes a while for your body to get use to AAS/sust. I don't know if that is the case or not. Anyway, I was also told that you can cut the sust with sterile cotton seed oil which may also help. I got some recently but as long as my injections no longer hurt I will keep things status quo.
I do feel your pain though. Up until about a week ago, I wish I had picked another AAS to use on my first cycle. It was also recommended to me to inject the sust every 3rd day so the test leves stay constant. I also switched from a 23 gauge 1 1/2 inch to a 25 1" for my delts and love it. It takes a little bit longer to inject but I hear that it causes less scar tissue. I just ordered some 18 gauge pins to withdraw the sust. BTW, my sust also comes in a 10 ml vial. It took just over 3 weeks to kick in but when it did I noticed it.
