Seeking support, new to this nightmare

Hi All,
Healthy active and 65. I walk (ed) 5 miles a day, eat well, blah blah blah! Woke up in the middle of the night mid December and have had 24/7 pain, redness, burning, numbness ever since.
The podiatrist said stress fractures so I am in a boot, however, it has not changed a thing and lack of sleep is getting to me. I am an upbeat optimistic human, however, WHAT IS HAPPENING!!! I am scheduled for blood work early next week. Seeking support as I have no diagnosis and am staying in the mindset with LOTS of prayer and meditation that this will resolve. My best to all of you. Thank you for listening to me rant! Hope
