Pam asked one of us to take a look at your question and answer session and see if there is anything we could add. I have to agree with Pam's assessment; it does sound like plantar fasciitis. The only other thing I would suggest is stretching your calves first thing in the morning and several times throughout the day, use an anti-fatigue mat if you are on your feet in one place during the day, toll a tennis ball under your feet several times throughout the day and evening to stretch it out, and see a podiatrist if none of these things help (including the NSAIDs). The podiatrist can analyze your step and determine the best type of inserts to use. This isn't unusual to develop this problem over the years, even if you've never had problems before. You said you are about ten pounds over weight. This, coupled with aging, can aggravate the problem.
