  5. I'm really confused about something. I was dealing with severe weakness and muscle pain, so I got tests done for vitamin B12 and vitamin D. My vitamin D level came back at 10, and my vitamin B12 was 176. After that, I took injections for both vitamins and started taking B12 tablets every night, plus the Uprise tablets for vitamin D every week. But after just 4 days, I got tested again, and my vitamin B12 level shot up to over 2000, while my vitamin D went up to 17. Is it normal for levels to change that quickly? What could be going on?

Nothing to worry about. Detailed history is always important
