Do all that you can that doesn't significantly bother you.

I am back to pretty normal exercise levels, took 2 years to get there but I did. I must monitor the duration of intensity more so than in my past but I'll take it!

What are you willing to live with symptoms wise that you recover quickly from is what I went by. Some exercise early on could take days to recover so I stopped and tried again later.

Nowadays symptoms do arise but not to the point of interfering with daily life so I accept it.
