Dear Larry & wife of 36 years....
Normally this is a sign that you've over done it a little.. a day of good rest and building back to an exercise routine… taking it slowly and listening to your body (blood in urine).
Then again you guys have not had a normal run with this.... so ~ definitely touch base with your doctor. Your healing/recovery stepping-stone is a little slippery right now… but I hope you know we are right there with thoughts and prayers helping to shore it up.
Let us know what you find out okay.
Keeping you close as you continue to move forward!!!
In Friendship ~ Lee & Buddy
