Man, I´m also afraid of that **** and evry time I feel somthing in my left hand I directly get upset but it has always been false alarm.

Once I felt real pain was a couple months ago in my left hand when I tried to pull my point finger finger down and it surley did hurt but funny thing was that it didn´t felt at all during the time I playd guitar. So i played instead of my usual 4-5 hrs 2-3 and the pain went away complitly after one week and I did not stop playn´. Now I´m OK.

If it hurts while you are playn´ stop and rest a couple of days. And since you play that much, your hand will get a mega rest and you´ll feel much better after. I don´t want to scare you but you may pay little pain now while you play but think if it increas. Than suddenly you´ll be forced to rest for a month instead for a week our so.

Also, warm up and get the blood circulation in your vains. Very important and don´t play in cold our while your hands are cold. It increases the injury risk dramaticlly.

But you´ll be fine soon you´ll see.
