I am living with weakness and muscle pain in the body. Is it due to low calcium levels?

Hi, Welcome to icliniq.com. I understand your concern. Low levels of calcium can cause weakness and muscle pain. If your calcium levels are normal, then weakness can occur due to viral infection. I suggest you do CBC (complete blood count), liver, and kidney function tests. After knowing the results, you can treat this condition accordingly. Vomiting can occur due to gastric reflux. I suggest you avoid taking spicy foods. Eat food in small portions. Do not sit after taking food. Go for a small walk and avoid taking heavy meals. If you have a feeling of vomiting, then take tablet Emeset 4 mg (Ondansetron) once daily. It prevents nausea and vomiting. Kindly send your reports after knowing your results and I can help to guide you further.
