In all due respect, everyone has to get a piece of the pie (as my DH would say).
My DH's accident is very early on and he has only seen one doctor/RN since he was released from the hospital. It was a special concussion clinic. Upon his evaluation 2 weeks post-concussion, he was not perscribed any meds. All they told him was if he feels a set-back or a relapse to give them a call. The hospital (not the cucussion clinic) perscribed him Xanax .5mg to take at night but that is ready to expire (good thing cause I heard that can become addictive).
The concussion clinic gave us a script for cognitive therapy and also to see a neuropsych. The cognitive therapy we are holding off on to see how he does on his own. The neuropsych. was for him to discuss the accident because he has sleep disturbances. Both of these types of therapy are available (if needed) but my DH has decided to decline for the time being, for he knows that the resources are there if he needs them.
There is no set therapy, time frame or magical cure for PCS. It is a healing process that can take months and they treat the symptoms until the body heals itself. My DH has been lucky enough that he returned to work 2 weeks after his accident with some restrictions (rest as needed, dayshift work only and no overtime). Now don't get me wrong, he comes home very tired and fatigue is obvious but something he has to deal with. He is just very lucky he works for a family-owned business who has been very understanding and supportive.
Good luck on your recovery and just remember, there are rarely any doctors out there that will tell you they do not need to see you. I'm still waiting for a doctor to cancel an appointment. If you feel you do not need the treatment that week, or 2 or 3, then make that decision.
