I just started taking winny for the 2nd time. The first time i would shoot it in my sholders and would hurt like a bit##. After reading and asking around i just now started to inject the winny into my tricep. Just now was my third shot. The first two where great one in the left then one in the right, not much pain at all but it looks like 2 golf balls are on my tricep when i flex. There is also a red circle around the injection. but after a few days the swelling and red circle would slowly go away.... But this time when i started to take the third shot (the second one in the left arm) I stuck it in and pulled back then when i tried to inject the winny it would not go in... so i pulled it out and started over again... i am using insilins with 1/2 inch Needles.. so now i stuck it in again and not even getting the needle half way in i got this shooting sharp pain that ran down my whole arm... so i pulled it out again and now i am f-ing shaking so after about 5 min i tried it again and got it in this time. i am just wondering if any of you guys no what happened and if i am doing something wrong i would greatly apreciate it!!! thanks
