Hi.. Based on the shared info, it is very very unlikely that chest pain is due to cancer-related issues. As CT chest was also done, no need to worry about cancer-related issues. Please consult a medical gastroenterologist also to rule out GERD. Please consult a Pulmonologist also with all the reports.
To help prevent muscle cramps, consider incorporating foods rich in potassium, magnesium, and
calcium into your diet. Examples include bananas, oranges, spinach, almonds, dairy products, and salmon. Stay hydrated, and consider consuming electrolyte-rich beverages, especially if you engage in strenuous physical activity. Additionally, ensure an adequate intake of complex carbohydrates, such as whole grains, to provide sustained energy for muscle function.
