Your medication, Amlong A (which contains amlodipine and atenolol), can sometimes cause fatigue. However, the temporary numbness, tingling, and weakness in just your right hand are less typical side effects and could be related to nerve compression, circulation, or your blood pressure. Because these symptoms are one-sided, I highly recommend having a gentle discussion with your doctor soon to rule out any underlying issues. They can safely evaluate you and adjust your treatment plan if necessary to help you feel your best.
