I have just started using and I had 2 shots.....taking 3rd one tomorrow...but my question is that on my right glute (where I took my 1st one) i have something that looks like a bug bite and it just showed up almost 2 weeks after....is it the way i did it....i did use a 1 inch needle and was told that it could be b/c of that so i'm gonna go w/ an 1 1/2 from now on....is it something i should be concerned with?
