Spinal Cord Injuries T10

Exercise for back injury?
Hi all,
I have had a bad back injury since January this year. I have my T10/T11 discs compressing on my spinal cord and I have T8 T9 L4 L5 out of place. Due to this I have become slightly immobile so I have noticed that I have put on a bit of weight. I have been eating healthy but I really need to start an exercise routine to keep my fitness up. I am able to swim, however, I am unable to swim laps for distances as this irritates my back.
Does anyone have any suggestions?
Have you had a thorough evaluation by a specialist – your family Chiropractor? He/she can advise you on appropriate treatment and an exercise program that is specific for your body’s needs.
Best wishes and good luck.
