Hey everyone.. Injected 1.5 into my delt Monday. Ive used this gear already. Monday evening it was uncomfortable which I expected. Tuesday evening I noticed my bicep was a little red and swollen and today is about the same. Taking Tylenol, last night I took a Doxy just in case and will for a couple days. Right delt was sore when I shot it but I didnt get the redness and swelling. Been on for several years and not had this, possible bad shot? Any thoughts?
