Plenty of us pilots have astigmatisms and glasses, not a problem as long as it corrects to 20/20 (ideally a little better than 20/20 so you have some room to decline with age)

Sounds like the spinal issue would not be a problem at this point. But you need to consider the future, ie how likely is that to worsen and put your medical at risk in the future?

Aviation involves a lot of incurred training costs and dues paying up front... you need to stick around for a long time to get your return on investment.
