has anyone else had extreme pain from an IGF injection?

I had my first injections today, 30mcg into each pec after my chest workout 1 hour prior. the pain is so bad that it hurts to touch anywhere in my chest and it is a constant sting. Nothing has ever hurt this bad before and that includes wintsrol, prop, t400, etc... wtf is the deal? I mixed it with 10ius of bac water as well. The only thing i can think of is that i just went tanning before my shots and I did use some lotion and maybe some of that got into the shot even though i used an alcohol wipe as usual. any thoughts???
