Hi guys I have a 10 day rotation of injection sites. Most times when I get back to the first site, there is still a lump there that is way too painful to inject. Should this be the case after ten days or am I doing something wrong. I’m injecting 60 units of levemir using the novo nordisk pen and bd micro fine needles. ( God forbid, I hope I’m not being a sissy. Lol)
