i love yoga. i would think as long as you are careful you can get back into it. maybe you could teach others who have medical limitations. for me modifications to yoga are required. sometimes the teacher doesn't get that. i once had one who said he would rather be doing pilates. i did not get anything out of it.

a friend has a relative in england who uses yoga in his physical therapy practice. done right it is the wave of the future. i send you only encouragement.
