Week 10 and only the 2nd time this happened when pinning, 1ml eq300 & .75ml t400, I got a weird sensation that shot up to my head. A kind of tingling, itching sensation in my neck, face, nostrils, top of head. Feels like a rush from injection that goes as quick as it comes. I don't think I hit a nerve because I don't feel it til I inject. Happen to anyone else?
