martin,

Welcome to NeuroTalk. Your fall sounds scary. Glad to hear you were not injured worse. Tinnitus and noise sensitivity are very common after a concussion. At just 5 weeks, you are still early in your recovery.

It may help if you slow down and reduce your activity level. The injured brain needs quiet rest with moderated stimulation. The Vitamins sticky at the top has some good information for you to consider.

My best to you.
