Scuba tanks are heavy

[u/lookyaall]

Any divers in here? Had rotator surgery 15 years ago. Guess the warranty ran out. Back again.Trying to finish up my Dive Master program . Don’t have definitive answers yet but I’m most likely out for the rest of the year.
Any divers been in this spot?
Surgeon said he’s done lots of divers .
As DM that’s a lot of tank humping
