vitamin b12 deficiency
"I started injections about a two months ago. The first month was an injection once a week. Now I go once a month. The only thing I have noticed is a huge increase in back pain. I had to go to the emergency twice! No one told me I might have pain. But it makes sense, my nerves are waking up. Also I feel seriously bloated. Sometimes my jeans fit fine, sometimes they are tight. It's not vanity, I am fighting diabetes with diet and exercise, so the weight changes are disheartening. Other than the pain and bloat I don't really notice much difference."
