My doctor told me that I have a severe vitamin D deficiency. I can not take any form of vitamins orally, They know there is the possibility of injections, but haven t found where to get it from, or if it needs to be made out of compounds to be able to inject it. I am not sure why it is so difficult for them to figure out, because there is a large teaching hospital in the area, but they haven t been able to find an answer. My vitamin D level is 11, and dropping. I can t stay online, so left my email. Thanks, Lauren
