FTN......
Welcome to NeuroTalk. Sounds like you have abused your body beyond its tolerance.
have you tried enteric aspirin for the arthritis and inflammation ?
I take it daily. The enteric coating prevents stomach damage.
Check out the Vitamins thread. I agree about the Nuvigil. The "try this" is more appropriately termed, Be my Guinea pig.
The links in Concussion's post do point you to the best in the concussion industry but they are still limited in how to help with recovery, especially in cases like yours and mine. My neuro suggested that my concussions have pushed my brain past the point where it has much ability to recover left.
Most of my current recovery since 46 years old have been learning work-arounds and accommodations. As you head into your 40's, you will need to focus even more on work-arounds and accommodations. The struggling brain does not learn work-arounds as well as the younger less struggling brain does.
There are plenty of natural anti-inflammatories available. Cumin (Turmeric) is good.
