Anyone know about ears?

[easy]

ds (nearly 4 1/2) has always secreted masses of very dark brown wax in his ears, but never had a problem with ear pain or such.

However, this weekend he has complained whenever putting a jumper on or off that it hurts his left ear. Doesn't complain the rest of the time.

I don't know how to see if it's an infection or what. It has the usual gunge, which he won't let me near to clear out.

Anything I can do before we see the Dr. tomorrow?

I'm going to get two pairs as a friend and i are going to do the treatment on each other. I don't trust my dh
