right leg pain

[curiousg11]

   I am a 63 year old male who has been  walking 3 miles daily for about 13 years. Except for occasional knee problems I've done alright. The last 4 months or so I've been experiencing pain in my right leg in various locations to the point where after about 1-1/2 miles into my walk I'll need to sit and doing various exercises to relieve the pain. on the return trip I'll continue to have some pain but am able to make it back to the starting point.
  I should note that the first mile is without pain. In addition I don't have pain while performing my regular daily activities.
  Walking is an integral part of my physical and mental health and I'm reluctant to give it up.
  Any suggestion will be appreciated.

First, congratulations on maintaining such an effective exercise program for 13 years!
I only wish I could be as successful, but arthritis in my knees limits my capacity,
I keep working at it ---
From the description you provided, the symptoms might be related to a condition known as intermittent claudication.   It is a form of peripheral vascular disease which may not have symptoms when at rest or during mild activity.  Pain usually occurs after more intensive activity such as lengthy ambulation or walking uphill or walking at a faster pace.
Resting eases the symptoms but they do recur when the activity level is resumed.
It might be beneficial to make an appt with your primary care physician for an evaluation.
PVD can be easily treated through appropriate medical care.  Left undiagnosed or untreated, it can result in blockage of the affected artery and result in more severe complications and disability.
Hopefully you will find resolution soon and you can continue your activity with no significant discomfort.
Best wishes ----
