I’m 2 months post Da Vinci RP surgery and I’d like to know when I can start using a pump. Ive read this is an essential part of recovery of erectile function and I’ve bought a Bathmate Hydro 7 but I’m a little worried I might cause damage by using it at my early stage of recovery. The consultant prescribed Sildenafil at the first post review (week 6) but did not mention the use of pumps etc.
