Hi there ~
You do not mention your age in your question, however dents in your head are abnormal. I would recommend that you get a CT scan
of your head to rule out any abnormalities. Also if you are Vitamin D deficient there are many ways to overcome the problem. Your first stop should be an endocrinologist
who should address your problem. You also do not mention what new med was used. However in any case please see a qualified doctor.
I hope this helps. Take care.
