Aw Mary... I'm so sorry to hear you're hurting so much... this has been a horrid bike year for me too... my mom's health was not good and I had my own series of health issues including 2 surgeries and a cut hand that resulted in a BAD infection and no using it for the last 3 weeks now. Sheesh, this getting older thing blows so far...
Hope the docs figure out what's going on soon and can help you get pain free and back on the bike... 4800 miles is amazing lady! Last year was good for me and I was only at 4000... this year barely over 1000. Ouch.
Gentle hugs and positive vibes for healing headed your way...
There is a fine line between "hobby" and "mental illness".
