Odd calf pain...can you help?

I have just finished a run themed week in my training program (from this site) for a HIM in december in NZ. Actually, it was supposed to be a swim themed week but I have swapped the position of the run and swim themed weeks to fit in with personal circumstances. But I digress...

Before I continue please know that I have had shin splints in the past, and have been to a podiatrist and been checked out, stopped running for a while and have been slowly building it back up. Shoes are about 6 weeks old, professionally selected and fitted with podiatrists blessing. No recurrence of shin splints so far. I stretch and ice when I finish runs and am receiving "The Stick" by courier tomorrow so will use that for more massaging. I get professional massages on my calves (mostly, sometimes upper legs) every two weeks. My logs are up to date if you want to check them.

So yesterday finished the week with a 90 minute run, along flat roads, out and back about 14km total. Where I could I ran on grass verge, sometimes concrete, sometimes asphalt (splits - 50% grass, 25% concrete 25% asphalt).

During the run I got an occasional sharp pain in my lower inner leg, in the middle of the calf muscle. It was jsut like a stabbing that lasted a second and then went away - no lingering pain or other sensation. I put it down to landing on a funny angle or something as I ran (like on a stone or something).

I felt great afterwards, stretched, showered, and then went with friends and sat in hot pools for half an hour to relax (we were on a mini weekend break away).

BUT...since then, every now and then - maybe every half an hour or so - I get a sharp pain back in the left calf. Comes and goes in a second. No lingering, and I feel great otherwise - even jogged a bit to catch some friends this morning, felt normal, no stiffness, nothing out of ordinary.

The pain doesnt come as a result of any particular action, for example, just sitting in the car this afternoon, not moving at all, it come - BANG - and left again, in a couple seconds. I hadn't even moved!

What is this? Driving me crazy, I hope nothing serious! Please help!
