If this was your first time injecting into your quad, believe me, you will feel it tomorrow! Thruthfuly, I didn't quit understand what your question was in your first post, but if you are asking if you are going to be okay, then it seems as if you are, but you should learn how to give yourself a proper injections. Like stated above there is no need to squeze any area when injecting IM. Just clean the area, insert the neddle, aspirate, inject slowly, pull neddle out and aply preasure on the injection site for about a minute.
