Reuseable pen needle size suggestions
I just switched to using a reusable pen and the company gave me a sample kit of different sized needles, I have had issues with the short 4-5mm 31g tips with my tesa leaking after pinning. Im pinning on my belly fat pressing firmly against my body and holding for 10 seconds after finishing the injection. Has anyone had this issue and had success with fixing it?
