Hi,
Here's my caveat, Everything that I will be mentioning involves the Canadian Heath care system so I can't say with 100% confidence that any of this would be the same for you.
I've had PT a number of times for different injuries. They include back, neck, wrist and ankle. I did PT because my Physician prescribed it. PT is not covered in Canada by the health care system but most employee insurance program cover it. Our running rate is about $60 for 1/2 an hour per injury spot. $80 for more than 1 Injury spot
I found that PT is much like a Chiro. They most likely will use electrical current on the muscles to loosen things up, then massage you and then give you a number of exercises to do at home to get better. You'll probably feel fantastic after your sessions but it's almost like a crack or heroin addiction because after you stop you probably will be in pain again. Then need to go to PT to feel better.
The positive aspect is getting the exercises that help with the problem area. And getting a number of them, then do those on your own. You should be able to get that done in about 3 sessions.
My 19 year old son, my 53 year old wife and my 17 year old daughter all did PT for injuries as well and pretty had the same results. All injuries have been sports related also.
One thing that did work marvelously for me and my wife however is Laser Therapy
Here is a link http://www.canadianchiropractor.ca/techniques/laser-therapy-a-guide-for-chiropractors-1001
It is usually done my Chiropractors around here.
They claim they make is that it actually repairs the cells and tissue. I've had it on my neck and wrist. My wife has had it on her back. I haven't had pain or problems in those areas for 2 years since I did the treatment. The doctors wanted to surgically repair my wrist after seeing the MRIs but Lasers able to fix the damaged tendons and give me mobility back. I can even do weight and Karate again.
The cost is about the same as PT, I needed about 10 treatments, which was covered by my private insurance. All you need to do is lie there and the machine does the rest
It might be worth looking at. I had nothing vested in that type of treatment. All I can tell you is that it worked for 2 50 year olds and apparently the methods are used by pro athletes for recovery.
