Hello, me again I am the caregiver to a man who 5 weeks ago had left lung removed,non small cell lung cancer stage 3.After surgery he still feels week (BEEN FIVE WEEKS) AND HE IS CONSTANTLY GAGING LIKE AND SEEMS TO HAVE FLUID. iS THIS NORMAL OR WILL IT GO AWAY,ALSO HOW OFTEN SHOULD HE BE PUFFING ON SPIROMETER AND HOW OFTEN TAKING WALKS,i AM SORRY TO SAY BUT DOCTORS DON'T SEEM TO TELL YOU TOO MUCH.THANX FOR ANY ADVICE

I would go see the Dr asap. I had same surgery 5 weeks ago too. If it is fluid, it should be addressed. Gagging is not normal.
best wishes
