A couple of days ago pain started in the ball of 1 foot mostly below big toe. Now making me limp. Getting over a bad cold. Is cold possible cause?

Gout? Doubtful that common cold would cause pain in foot below big toe. More likely culprit in middle aged men is gout. Go see your doc for exam & diagnosis. You may need blood test to check your uric acid level. Goal is <6mg/dl. Check online for low uric acid diets.
