Ouch! My dad fell last year and broke his pelvis and just underwent a total knee replacement 2 weeks ago today...so I have learned all about the process.
I don't know if you have family/friends nearby to help or if you need anything, but I am in Sacramento and driving right through Martinez to go to Walnut Creek for business on Thursday morning. Otherwise, hope you have a quick recovery and get back to Belize as soon as you can!
