Hi and welcome to Healthcaremagic. Thank you for your query. I am Dr. Rommstein, I understand your concerns and I will try to help you as much as I can. Yeş, it is uncommon to feel pain on th eleft but cholecystitis may be accidental finding and it may require specific treatment. In acute phase, you need to take spasmolytics, avoid fatty food and rest. In case of progressive pain, go to ER. Your symptoms may be suggestive of gallbladder stones so you should do at least ultrasound or CT scan to evaluate it more accurately. This is caused by stone in bile duct and is very common condition. You need to change your dietary habits first. Need to avoid fried food, carbonated drinks, coffee, alcohol and spicy food. You should eat more milk products, vegetables and boiled food. If there is no improvement on lifestyle or dietary changes, then surgery is recommended. I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards. Wish you a good health.
