Thank you Mark and Sitke for your quick reply.

I asked my Neuro for the hormone tests but she denied saying that hormones imbalance is not related to PCS,its not routine to check it and it would not be of any help. I can not do the test with out referral.

Even before injury I had trouble sleeping, I do not generally get good restful sleep. Any suggestions for good night sleep?

Last week I was feeling little better so I worked more than usual and did jogging for 10 mins or so. Since then I am experiencing more dizziness and fatigue PCS is really a life changer.
