yes , quit using the kit warm water alone is good enough. To much of the chemicals in the kit can cause damage. If you have over used the kit by all means see a Doctor.
I have had this problem before, Just take the little bulb and keep Flushing with very warm water only. I did this for along time ,and finally A big chunk came out and I haven't had the problem again. Now I flush my ears every time I take a shower. No Q-tips that is how I believe I packed it in so bad.
I hope this works for you ,I know how annoying this can be.
I did learn from this though, I now understand how people with hearing problems feel.
I put a white hand towel in the sink as a filter so I could catch what came out, this gives you an idea of your progress. You might have to repeat this 2 or3 days in a row as the warm water softens the wax, twenty to thirty minutes a day till clear is enough, You don't want to over do it and make your ear raw.
GOOD LUCK with this.
