The first thing is - please don't clean your ears with cotton buds, you are very likely doing more harm than good and it is possible that you might be causing some of the bleeding in your ear. By cleaning your ears, you are removing the protective layer of wax in the canal and you are also interfering with the natural cleansing process of the ear. Concerning the blocked feeling in your ears, i would recommend that you see an Ear, Nose and Throat specialist if it doesn't clear up.
Then lastly - if you are working in a high noise environment then it is very important that you should use noise protection and that you have your hearing evaluated on a regular basis.
Please let me know if you need any further information
