Dear Vivster!!!
What good news you are able to take a bit of a walk and notice the benefit of the stim although there is still a bit of insertion point irritation. Be good to yourself.... walking is good. Remember BLAST as you walk. Try not to schedule a tennis match this week
even though you may be tempted to do so. Keep a journal of those experiences you note so you are able quickly and reliably with demonstrative evidence to report back to your doc and rep.
Lastly, know that I am prayin for ya,
