Sorry for the frustration momof3
Swimming is about the only exercise my body can tolerate at this point, so I was very anxious to get back to swimming after my post-op restrictions were done.
After 8 wks, Dr said it was ok to swim.....but he did say to make sure to turn OFF the stimulator. ? He's always in such a hurry and I feel like I'm talking to the back of this guy's head , so needless to say he didn't expound upon the subject and I didn't chase after him for more details.....

So, maybe we can try Googling that question

The input Hannah gave makes sense, so see if you are able to still swim with the stimulator turned down lower..... geeeze, I'd had to see you get leg spasms and cramp up while in deep water.......that would not be good!

Not sure about the altitude change either. Hopefully someone will come along with more input......
