Hello from JustAnswer.
There are several possibilities to consider in this situation.
Excessive ear wax can cause pain in the ear and decreased hearing, but it would be unusual for ear wax to cause hyperacusis. However, interventions to irrigate or scrape the ears to remove ear wax may cause or exacerbate hyperacusis. The application of drops to soften the ear wax is typically well tolerated. In addition, it usually will be well tolerated to allow gentle flow of warm water into the ear, such as in the shower. So, ear drops would typically not aggravate the problem and there is no reason to stop using the drops. However, if you have tried home irrigation, that may be contributing to the hyperacusis.
There are a couple of other options that you can try at home to ease symptoms. It may help to use an over the counter antihistamine, since the blocked ears may also be related to fluid in the middle ear. It also may help to use an over the counter anti-inflammatory medicine, such as ibuprofen or naproxen.
As for whether you should be seen in A&E, that would depend upon the severity of symptoms. If you can get some improvement in symptoms with the above interventions, then it may not be necessary for you to consider being seen emergently. However, if the symptoms are persistently more severe, then it may be necessary to be seen.
If I can provide any additional information, please let me know.
Your GP will make an assessment based on what can be seen, but in a patient with an excessive amount of ear wax, there usually can only be a limited amount of the ear drum that can be seen, and frequently none of the ear drum can be seen well. And if there is non-infected fluid in the middle ear, the findings can be subtle, and consequently difficult to detect if the ear drum cannot be seen well.
It is a good plan to try these interventions and reassess tomorrow.
