Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
I just injected myself with vitamin B 12 in a vein in my buttock area I did draw back and didn't see any blood but when I pulled out the syringe a lot of blood came out and I felt light headed and nauseated very quickly. Do I need to worry about anything?
