What Causes Ear Discomfort In A Child?

to me this is gonna sound foolish but here it goes. my son is having problems with one of his ears. tugging it, trying to stick his finger in it, and other such things. he is two but this is not normal for him. we went on vacation a week or so ago and it was warm at the cabin we stayed at so we left the porch doors stay open so the kids could play outside on the enclosed porches. our son started crying one night and tugging on the ear and we washed it out with some mineral oil. the next night we used sweet oil. we can not see anything oursleves but i did notice while we were at the cabin that the wood roaches were crawling about outside. well, duh, i know it s a cabin and it s in the woods so that is expected. his ear has never bleed or anything but he has been having a lot of wax coming out of the ear and tugging on it more thatn he has ever done before so i think there might be some kinda of bug in it. my husband wants to get it out ourselves if there is one there but to be truely honest....I don t feel safe about it. We are going to buy the octoscope that is sold in the stores and see if we can see anything today. I have almost made up my mind to just take him on to the doc monday. I am so scared, I don t want to damage my son s hearing with trying to get one out if there is one there. To be honest I am gonna feel like the world s worst mother if there is a bug in it. i guess what i m asking, is if i am right in just wanting to take him to the doc and let them get it out?
