Forgive me if this is the wrong place, but I'm brand new here and looking for some help:

I've long suffered anxiety/depression/panic attacks symtoms. (47 year old male.) Just recently went off prozac, but still on xanax. Also have had some low testosterone scores recently. I also was just diagnosed with a b12 deficiency by a Neuro, who ordered tests after she noticed that I had hyper reflexes in lower extremitis but slow ones in upper extremities. An MRI to rule out MS type things was normal, but blood tests revealed a slightly low b12 score of 355 I think. She said I should get monthly shots -- and that I would feel better in six months.

A few questions:

1) I've been feeling often cold and sorta stiff in the upper body since the shot 10 days ago. Is this all in my head since I was told about the slow reflexes in my upper body, and I'm a bit of highly suggestible hypochondriac? Or a side effect of the shot? Or a symptom of the underlying deficiency?

Are there any real side effects to these shots other than immediate allergic type reactions? I think I've been more depressed and anxious since I got the shot, and so I wonder if there's some connection.

2) Is a once a month shot enough?

3) Why would she say it would take six months to notice improvement? I read accounts of people feeling better in days.

4 Her office called me to reschedule and postpone my next shot since the doctor will be going on a long vacation. This means I won't get my second shot until 2 months after my first. They say this is not a problem. Is it?

Any thoughts on any of this would be appreciated. Thanks.
