Pins and Needles all day! Is this related to anxiety?

I suffered a bike accident 5 weeks ago and developed post concussion syndrome. My anxiety was the worst of all the symptoms. I had a constant fear of dying and was afraid to go to sleep cause of fear of dying. Didn't sleep very much for over 3 weeks. I would wake up having a full blown panic attack that I couldn't see and would start freaking out. I started googling every symptom I had and was convinced I was dying. 2 weeks in I started taking Zoloft. I started getting tingling all over around this time. It was more flutters at first but now it is a pins and needles feeling. It will be in my toe then my arm, then my face, then my thigh. It constantly shift and goes on all day. I shifted from Zoloft to Prozac after a week on Zoloft cause I didn't like the flushed feelings I got in my face. Then I got put on trazedone to help me sleep almost a week ago. I visited a neurologist and he says the tingling is anxiety or lack of sleep. I had an MRI and CT after the accident and they came back normal. I just had a full physical and blood work was normal. No vitamin D deficiency. Any advice on if this is anxiety would be great. I am starting to feel less anxious this past week now that I'm sleeping but the pins and needles is still there. How long til it goes away?

Ever since my breakdown in February, I've had tingles and pinches all over my body. They are finally starting to go away, but I still have tension all through my neck, that runs through my head. It's an awful feeling, and I still haven't figured out how to deal with it. I get bi-weekly massages, and they seem to help quite a bit.

Thank you for your response. It's nice to know that it does get better but may take a while. I keep thinking I need to call the doctor cause it's not quickly going away but I will be upping my medicine per my psychiatrist and wait it out. I too am thinking about going to get regular massages to help.
