Spot injecting into delts and getting swelling just below the delts. Not an infection or anything, just slightly swollen below the injection. It goes away after a week or so, but it's noticeable by looking at them that their shape is different while they're swollen. Would like to keep spot injecting them but dont like the swelling. Its the side delt that's involved here. Using test and tren, no more than 1.5cc at a time. Should I be massaging it more post injection? Any thoughts?
