Long Lasting Sap

As I was driving around Lake Tahoe the other day, I stopped at a beach. Nice, cold but nice. The trees where huge, and so were the pine cones. I picked one up that was roughly the size of my head (which is large). When I went to put it down I realized extra large pine cones come with an extra large ammount of sap. I was able to wash the sap off in the lake but then had some transfer of sap. I went to make a call on the cell phone, passed sap on to the phone, and then sap to my sideburns. This sap has been on the side of my head like cement for almost four days now. Someone told me to just comb it out. The thought of that pain and bald spot scares me.
