Concussion

Once, yes. More than a decade ago I was knocked down by a wrong-way bike while running in Beijing. Hit the pavement and may have blacked out for a minute or so, pulled out of traffic and helped onto the subway home by a rare good Samaritan (not common in that city). Dizzy and nauseous for maybe a day, then about a week of having a sore head, especially upon exertion. Therefore I would avoid exertion. Your body is trying to tell you something. When you do get back to exercising, start with easy stuff like walking, swimming, or easy spinning that doesn't get your heart rate up too high, or involve pushing against resistance (i.e. shoveling snow, lifting heavy weights), or a lot of pounding. Beyond that, just listen to your doctor.

More than once. Rest and time helps. You should have received specific instructions from the ER or doctor about when to resume activities and about what to do and not to. Trying to do things prematurely is really not good for the brain. You did see a doctor right?

yes i seen the Dr. Basically told me this could be something between 10 days and a couple months. Told me to just take it easy for a while. Not really easy for a guy who always needs to be on the go lol..

Depending upon the severity of the concussion, you should consider not resuming even modest amounts of strenuous activity until you are a symptomatic for about a week or so.

Our policy is not to release people to activity until seen in follow up in two weeks.. There can be a number of mild cognitive deficits that may not be obvious. Persistent headaches, nausea, and difficulty concentrating would be common symptoms suggesting your not ready.

The problem is that there is _no_ way to tell how bad/long the symptoms will last.

A concussion is primarily a metabolic disorder. What we recommend to our athletes is to get lots of rest, both physically and mentally, and drink lots of gatorade type drinks.

We also would be running people through a neurocognitive assessments (e.g. IMPACT) and hold them off from activities until they return to baseline, although it actually takes a M.D. to officially allow them to return.

Since I'm going to assume you don't have a baseline I'd suggest that you take it super easy until you feel 'normal'. Then _slowly_ return to activity. If there is _any_ sign of discomfort or issues stop immediately and rest longer. You can't rush the process and returning too early can be very detrimental in the long run.

Best case, you're good to go next week, worst case it's 5 months before you're normal. Just for an example a friend in our club crashed her bike on our spring break trip last March and ended up concussed. She wasn't back to full normal activity until October, her crash wasn't even that bad, just a low speed fall while wearing a good helmet.
