[|Human|] At intervals, I feel dizzy and light-headed once or twice a day.  My doctor ordered Propionate nasal drops in December.  More recently, I also have shaking in my right leg at the same time.  The shaking is visible to those present with me at the time.  I am on chemo presently, but I feel good otherwise and have no other heart, lung or otherwise problems.
[|AI|]  Hello! Welcome on Chat Doctor ! Your symptoms could be related to chemotherapy adverse effects. I would like to know more on your past medical history and the reason that you are on chemotherapy. Anyway, considering the fact that you are on chemotherapy, I would recommend performing some tests: - a brain CT scan or MRI-complete blood count for anemia-blood electrolytes- kidney and liver function tests-thyroid hormone levels for possible thyroid gland dysfunction- vitamin B12 and vitamin D plasma levels for possible deficiency. You should discuss with your doctor on the above issues. Wishing all the best,
