I am a male,68, overweight. Both hips and knees replaced and both rotator cuffs repaired all in the last 11 years. I feel ok. I was walking 3 miles a day 2 years ago. I also walked 18 holes on flat courses. I take meds for high BP and high cholesterol, along with a baby aspirin I have been on these for about 25-30 yrs. I recently( last yr. or so) have developed serious finger and toe nail deterioration. I have developed loss of leg hair and slow recovery from leg scratches/cuts. I have severe 'cramping' in my rt. lower calf. My PT said it was "like massaging a cinder block " it was so hard ( and painful ). Whats my next move ?
