Hi Ffxlulu,
The nerve pain started after the first week but now at the beginning of the fourth week it is now going away.
I began walking around on the first day to a grocery store by OZ Clinic and then to Starbucks next to the hotel on the second day. I also went to the gym in the hotel to do some exercises for my arms. I walked very very slowly and then came back to my room to do the stretches.
However, this may not be the best idea for everyone, I have been a dancer for years so my muscles are very used to stress and being constantly in use. I think that everyone should listen closely to what their body tells them regarding how active they should be.
Take good care!
