Roger, sounds like your constantly pushing your injury. Don't run on it, wait untill you can't feel it and then wait another 10-14 days. Seriously, you will not do your running any good by running on an injury like this, Every time you run on it, even for a couple of miles, you will be putting recovery back by 4-5 days (or even worse) unless you're 20 or under.
I've had the same, and battled with it for 6 months before biting the bullet and taking 8 weeks off running. Sorting out any quad imbalances, stretching out the calfs, hamstrings, quads and hips, and maybe foam roller (i don't know if this helps but it hurts so it feels like it should) whilst recovering should do the trick.
This is from experience rather than any actual know-how.
