Hi I know exactly how you feel. I had a stage of the recovery that was exactly like you describe. Every little head bump brought back symptoms which I thought I had already recovered from. Eventually symptoms have improved despite the minor head bumps and with each bump I also noticed slighter symptoms than the bump before until the symptoms were manageable. This stage lasted 7 months. I am still wary of a big bump to the head as I am sure this would cause a concussion but the small bumps don't seem to set me back any more. The neurologist told me I will eventually heal from the injury (I had a concussion) as I am only 36 and this does seem to be happening, albeit not as quickly as I would have liked! Over time you will find some stratgies that help you recover faster from the small bumps, what really helps me is if I can stop what I am doing immediately and lie down (not always possible because I have kids!!) then after a couple of days starting to gradually stress the injury with plenty of rest in between. Exercise helped me a LOT with my original injury, I had to start with 1 minute, then rest for 1 week till the headache went down, then work up from there but after about a month I could exercise for half an hour and my overall symptoms were much improved too. And fasting has helped me a lot--i started a separate thread and it didn't seem to popular an idea but that is what just helped me. It took several months of trial and error to find what worked in my case and lots of patience to let the brain do its thing, so hang in there!!
