DaKajun what size pin did you use 1 1/2 or 1"? We are about the same size first time I used a 1 1/2 and had some discomfort like you the second pin on opposite side I used 1" and none! So for me that location only requires the 1" pin.DaKajun said:Did my first ventro glute shot yesterday evening. i did have a little discomfort going in and its sore today. It is virgin muscle and was first try at it. I'll give it a few more tries and try and fine tune the spot before i give up on it.
