Anyone else had issues with the insulin pen (in my case Kwikpen for Humalog) getting stuck or causing inaccurate dosing? I just started a new pen a few days ago and when I inject myself, it sticks at the 1 or 2 unit marker and won’t go any further. I’m finding myself thinking I injected 8 units when in reality I may have only done 6. Or the opposite where I think only 6 went in so I inject again with two units and over compensate. My numbers (and me) are suffering. Should I just throw this one away and start a new one to be safe?
