wow - you've done it! well done Jeff!! i apologise for not clicking into this thread before now, i just didn't realise your surgery time was so soon (for some reason i thought it was June) duh... sorry buddy.
anyway, i'm delighted to hear it went smoothly and that you're home & eating/peeing/pooing etc
sorry to read of the gas & pain you've had - i think it's quite normal to have these post surgical hiccups. you went home quite soon after surgery, it seems, and i think a lot of my initial pain & such happened when i was still on the ward. i remember limping up and down the ward all night trying to disperse gas pain. one thing that does help me when i get trapped gas is hot water - just sipping it slowly seems to really move it along so it can pass out through the stoma, or come up the other way. and massaging my tummy helps too.
re disposing of the used appliances, i also use the fragranced bags that come with the appliances, or you can buy nappy (diaper) sacks at any pharmacist, which do the job just as well. make sure the appliance has been emptied before you dispose of it, and the odour shouldn't be a problem then.
showering - i think in all the years i've had a stoma, i've only showered a couple of time with no appliance on. i don't like the feeling of hot water actually on the stoma, so if it needs changing, i do it straight after the shower/bath. if it's not due for a change, i just dry it as much as i can with a towel, then give it a quick blast on low heat with the hairdryer.
at the moment, i'm getting around 5 days wear from each appliance, that's with showering every day - which is amazing (thanks to my stoma nurses), as previously with the old ones i was changing it up to 3 times a day!
keep an eye on your fluid intake now that you have an ileostomy - we are more prone to dehydration simply because we lose more fluid than before - our colons have the main job of taking fluid back into the body from feces, but now you have a stoma that fluid just comes out.
keep up the good work, Jeff - sounds like you're doing great!
