How come I quit smoking so easily?

This is probably a verbs of the inner costal muscles in the rib cage. And it will hurt exactly close to you describe. It's very knotty to recover from this type of Muscle strain. I recommend you grasp massage dream therapy or chiropractic care as soon as possible to relieve the strained muscles. This will oblige you start to recover vastly quickly.

If you perceive that it's something worse see your medical doctor.

When i run, even for a minute or so, my legs and thighs get REALLY sore!?

I agree - to swot more about muscles read The Trigger Point Therapy by Davies.
Natural muscle relaxers are molasses (a couple of swigs) and bananas because they both contain magnisium and potassium.
