for more details: it's a mild pain that becomes unbarable because of it lasting for a few minutes. the Location is in my lower left leg. and as I said it's completely at random, I can just be walking the dog when I get it

Sorry if this isn't much help, as I can't really come with anything resembling a proper diagnosis. But when you're in pain I suggest you try to massage the area, or put some ice on it which may have a soothing effect. You could also try painkillers if you think it's necessary. 

But in general you should probably see a physician, as you'll want to find out the seriousness of the condition.  

that for the tip tartar, I'll see to thatif it gets out of hand
