So pinned my left quad last night after not doing so for a while. Def didn't pin in as deep as I normally do but I also don't have any fat on my quads. Also pinned a little more towards my lap area then I usually do.
Hours later though became pretty sore. Today little more sore. Slight red and hot to the touch.
Started coming down with a cough yesterday morning and today feel like I might have a slight cold maybe just coincident. Never had a problem before. Have pinned with this vial before in my glutes and it's been fine.
