Hello, there might be something going on separately along with gall stones. For which, according to ur symptoms you must have to go through some investigations. Before start with the investigation, a doctor needs some basic information regarding patient that will help to achieve the goal of investigation and treatment to be done.

Hello,
Thanks a lot for posting this question in this we site

First of all let me inform you that a given medical symptom or condition may be due to various causes. For example headache can be due to migrain, brain infection, tumor, problems in the blood vessels of the brain and so on. This also has to be interpreted as per the patient's age, sex and the presence of other comorbid medical conditions.
Back to your question, dizziness and sense of imbalance can similarly be due to many causes. For example it can be due to positional vertigo, called as BPPV, can be due to heart problem like slow heart rate, can be due to minor stroke in the brain and so on.
I assume that you donot have vomiting, headache, or other neurological symptoms to suggest a wserious neurological problem. My sincere advise to you will be to get a neurological check up with alocal neurologist and he will tell you if you have any neurological problem based upon the clinical examination. This clinical evaluation will tell us if there is a need for CT scan or not. If all these are negative , there is a strong possibility of BPPV-Benign paroxysmal positional vertigo. This will imrpve with brandt daroff exercise. Endonee generally wonot cause these symptoms neither your stones
Hope this clarifies
