Thank you Alexis.. Oh yes, I know sadly the risks of infection in anything we have done, I am a walking infection right now!! I get a cut, I get an infection.. I am on round 5 of a different antibiotic for a severe nasil and sinus infection, at the same time an incision to strip one of my many veins opened and became very infected.. Lack of common sense DRs and quickness , I believe the leg is the result of the sinus which may sound crazy but I used a menthol inhaler Benzadrix? 9 weeks ago, one inhale, burnt a hole in my nostril.. It is so infected and painful, went to my entire left side, Friday I see the ENT after waiting and ER visits,, Ever since I had cancer srage 4 and chemo I have had 9 surgeries and never had an infection,, Now, I touch something and I am an infection, especially my skin,.With regard to the Box, I never thought about it doing what happened to my Mom , that thing was beyond nasty when the surgeon took it out. but I have no clue how long it was in there infected before I saw the hole in my Moms back. I hope that your hip replacement is well and you are walking well. Both of my parents had replacements, Dad up and walking the same day,, my Mom I think the hip was ok. she never really did any of the PT all the way through. On anything she had done.. My obsession with 2 hours on the treadmill is well ingrained in me to do so.. sometimes I just hate but I do it.. I have been walking all over the world and every city I went to .. my entire adult life, Drs believe that being so active is part of why I am still here with after the cancer I have . Going through chemo I used to do 3 hours. full incline.. I have slowed down a lot speed wise and incline, i donlt have the breathing or stamina I used to. I accept it as I can;t change it,, But I encourage you to try to stay on the treadmill just do it slower.. Find A good movie or a ridiculous silly reality show to watch and the time will flow by.. Being as though I live alone with the Dog and cat ,,no one can judge me so I will eat my dinner while on the treadmill. otherwise I would not have the time,. Forces me to eat slow but be careful not to choke!!! Best to you and I wish a pain less life!! J
