Hi I am new here as of today but my issue is rather urgent... we sort of. More uncomfortable than anything. My Doctor recently switched my Lantus for Levemir. I use the same dose of Levemir (74 U) as I did with the Lantus. With Lantus I would get a small quarter size wealt and it would be gone in 24 hours. With the Levemir I have wealts the size of a small orange! They last for 3-4 days. I was wondering if anyone has had this type of reaction. Other than that it works just as well as the Lantus. I am worried that I will end up with severe cellulitis. Opinions?
