There are millions of individuals ranging from younger ages to retirement age who have found that their sense of dwindled as a result of natural growth.
In which case one very popular option is to get a hearing aid.
However sometimes the hearing aids will come with moulds that do not fit the ears too well, and in some cases will result in bleeding and/or infection.
Initially when one gets these hearing aids, the moulds are soft, close fitting, and have little to no feedback.
However after a while the part of the ear that the hearing aid latches itself onto may become dry and compound that with the fact that as you are moving (including slight movements of the ear itself every now and then), it will cause erosions of the skin.
In some cases it will even lead to infection in which case you should stop wearing the hearing aids for a while.
If you try it again later on and still experience problems, you may want to get your moulds redone.
Some people in the mean time prefer to use special creams to reduce this friction as some sort of moisturizer for that part of the body.
In some cases, this problem will go away by itself once your ear gets used to the fitted-moulds, but in the case that the problem remains bad, it's advisable to get back to have your moulds refitted from wherever you acquired them from.
