I've done some water exercise. One of the benefits is your head can be supported by floatation so you can relax your neck muscles. This may allow the neck to decrease any inflammation. The low impact twisting of the neck and upper spine may also help with cervical spine issues.

The low impact exercise can be good. I did lunging. I would lunge (walk with strong leg pushing) the length of the pool for almost an hour. I did almost 50 25m lengths in 45 to 50 minutes. That is about 3/4's of a mile.

Unfortunately, access to the gym and pool is no longer included in my health care plan. I have not tried the new pool that is much farther away.

I've been doing pool therapy -- not directly for PCS but for the sciatica that came on while I was recovering. They have me in a pool with a treadmill and then are teaching me other exercises I can do independently in a community pool.

I love it!! I definitely feel better when I exercise, this is good total-body work, and there is NO impact.

I think that regular swimming might be too much exertion, but walking and doing suspended biking in the water is AMAZING.

I am really looking forward to getting in the pool eventually. I've been walking more recently (close to an hour a day), so I'm feeling more hopeful about trying different forms of exercise down the road.

The two concussion specialists I've talked to said that pool work can be good, but be careful of too much pronounced head movement (in classic freestyle, for example), at least early on. One of them also commented that swimming can involve more exertion than people think, as you're essentially hauling a large and heavy mass of water with certain strokes.
