Hi. The dizziness that you are describing along with loss of sensation on your left side points more to a neurological cause rather than an isolated ear problem. It is possible that after your surgery there is residual inflammation and swelling pressing upon or stretching some areas of your brain leading to these symptoms. If you have fever along with dizziness and no hearing symptoms it can be a viral vestibular neuronitis which will resolve on its own in a few weeks. If you have associated hearing loss and dizziness then you must get a pure tone audiogram to rule out ototoxicity to any of the medications that were provided to you. The pain in the right ear can be due to something different altogether. My hypothesis is that since you must have had the surgery under general anesthesia, where there could have been some minor injury in the throat during intubation which would have triggered off an inflammatory process. Throat inflammations are known to radiate pain to the ear. We normally have fluid in our inner ears and it is necessary for normal function. Even though the fluid within the cochlea is connected to the csf in the brain via the cochlear aqueduct it is very unlikely that a buildup of fluid especially after a shunt would cause these symptoms. I suggest giving it some time and patience and it should settle.
