My cartilage in my knees are bad and i here the cracking sound also and my doctor told me that it's the cartilage and i also had ex-rays . I would like to go back to the gym and work out again but my bladder fell to where i can see it and i do not have ant leakage and i have been seen by a doctor and he asked me why i wanted something done i told him that i dont want my bladder done there and it causes alot of problem with my sex life with my boyfriend. When i go back to see him in Feburary iam going to tell him that i want the mess done but he also said that the mess also cause problems but it least my bladder will be back up there anyways back to exercises if i can do them what can i do and for how long because i can stay on the stair climber for 1/2 hour and i dont want my bladder to fall out i know of a women that her bladded fell out. If i cant do any exercises can i at least life weights sitting down. Also what are the chances of my bladder falling back down if i have the mess done. Thank you Kathyj79
