Patient: I have what feels like 2 knots on the left side of the back of my head and one knot in the back on the opposite side. What could it be?
Doctor: Thank you for writing to us.I think that you have injured the back of your head. You can try to ice the area fo 15 mins at a time to see if it helps. If it does not reduce after 3 days, please see a Doctor.All the best.
