Before Covid in 2020 (I was 73) I was hiking 5-10 miles in the mountains of southern Arizona. During Covid I could not digest food although my lungs were unaffected. I lost 25 pounds (200 to 175) in 10 days and lost 4 teeth due to calcium loss. During the next 11 months I worked up from 1 mile to 3 miles on flat ground. One day I tried 4 miles with about a gain of 200 feet in elevation. I felt unbearable pain in my left groin for the last mile and could not walk for several weeks afterward. I then spent 3 months in therapy at the VA and worked back up to 1 mile. Since then I have slowly increased my hikes and yesterday walked 9 miles with slight elevation gain. My goal is to hike 10 miles next week on my 80th birthday. I still have tendon problems in my left groin and x-rays show I have osteoporosis in my hips and knees although that pain is slight. Sometimes I will be sitting in a chair and feel unbearable pain in my left groin tendon (not pain in my hip) and have to wait until it subsides before I can stand up. This event is irregular, unpredictable and very annoying. I rarely but sometimes have the same symptoms in other joints. Anyone else have a similar hstory? Please poste here because when I tell my doctors, they just shrug their shoulders. fishwithak
