What Causes Pain And Echo In The Ear After Lavage Procedure?

I had an ear lavage preformed and this caused steady, slow ear bleeding for three days. A doctor said there was no obvious TM damage. This was about 3 or 4 months ago. Now occasionally when I hear a sudden sound I hear what seems almost like an echo in the ear in question that is very painful. This echo can sometimes occur after a very loud cracking sound or, sometimes, after a relative quiet sound. Also, since the lavage, I have been having a crackling and popping sound in the effected that sounds, to me, like TMD in the joint on the same side as the affected ear.
