Thank you...very informative. I do walk...3-4 times a week 1.25-1.50 miles at 3.0 speed.Walks usually last about 25 minutes each. I have an app on my phone that measures it. I am going to call my PCP tomorrow and get a referral to an ENT. It is something that needs to get done. Will talk with PCP about the Mupirocin. God bless!!
