this morning while I was working, at first I could hardly see, then it got better but now my arm is numb.

It is important to take any symptoms seriously and seek medical attention promptly. Symptoms like numbness in the limbs or changes in vision could be related to serious medical conditions like a stroke or a transient ischemic attack. It is crucial to consult a healthcare professional for a thorough evaluation and proper diagnosis. You may need to consider changing your contraceptive method if it is found to be a contributing factor. Make an appointment with your family doctor or a healthcare clinic to investigate the source of your symptoms further. Take care of your health and prioritize seeking proper medical care.
