Darn man! Sorry
I tore my hamstring when I was 21 I think, horrible injuries to deal with.
For 2 years I did nothing but rehab. First physio, ice, heat,
Then stetching
Then light excercise
Then intense message to break up scar tissue, ice and heat again
Then when I could it was the recumbant bike
It was all I could do all day was physio related for 2 years.
I hope your doing well and take care of that injury so it doesnt haunt you all your life
