My Left Lung Collapsed May 20th. I Didn't Go To

My left lung collapsed May 20th. I didn't go to the hospital until May 22nd and had a chest tube inserted for 6 days.....there was a lot of blood on my lung and it was not expanding on its own. Tomorrow will be 2 months since the tube was removed and I want to get on rollercoasters a week from today with my daughter. Is it ok or too soon? Also, I have that hand held device that I breath in to and I'm at 1700 on it (it goes to 2500) so all seems well.
