a) Probably not wise to mix remedies.

b) It could be deep rooted, compacted wax. Do you poke anything down there? That can 'ramrod' it into a compacted block.
My advice: Tonight, lie down on your side, head down, put some hydrogen peroxide in. If it fizzes and you feel movement within the ear then its deep compacted wax. Give it a minute or two, then before it has stopped fizzing, get up and lean right over the bed, head down. That should get things moving and the still active hp should help break things down on the way out. Sleep bad ear down so it can drain. You might need to do it for a few nights but it should work.

c) I think you need to back off after you've tried the above for a few nights. Let the ear dry out.... You've put so much stuff in there, you've probably turned it into a marsh!!! The ear should be dry. When its dry the wax will crumble.
