This sharp pain in your upper right belly radiating to your back can be very uncomfortable, but please try not to worry. This type of pain is commonly related to the gallbladder, such as gallstones. Since you take Stanlip (fenofibrate) for high triglycerides, it's helpful to know that fenofibrate can occasionally increase the risk of gallbladder issues. Another possibility could be mild inflammation of the pancreas. To keep you safe and comfortable, I highly recommend having a doctor evaluate this promptly. A simple ultrasound and some routine blood tests will help find the exact cause.
