Its been 4 months since i suffered a a concussion and broken wrist. Most of the headaches and dizzyness have faded and my main culprit is ringing in the ears that i am now most attentive to at night. The frequency of the ringing can intensify after some cognitive/physical activity which is still a bit of a letdown.

I would like to get back in training with 1-2 hours of lifting/running this month and since the main remaining symptom is some ringing in the ears would you think it is ok to start exercising for a marathon that takes place in the fall?

The only comparison for physical activity i have is john jaso of the oakland a's who i researched was not allowed to resume play until his post concussion ringing in the ears cleared after the season...

I dont want to relapse however i do want to start regaining strength.

Thanks to all for their feedback. Greatly appreciate it.
