Temporal arteritis is a definite possibility based on your symptoms. Bell's Palsy also is possible, as are atypical migraine and a remote chance of tumor or aneurysm. Your best approach is to request a neurological evaluation. It is still early in the development of your symptoms, so complications such as your concern about blindness are extremely unlikely. However, the best result of treatment will come with early intervention, which is why neurological evaluation is encouraged. Don't hesitate to discuss your concerns in depth with your physician, if a referral is required. It would be helpful to you and to your physician(s) for you to keep a daily record of your symptoms, when they occur, how long they last, what you are doing at the time they occurred, as well as any other concerns that may occur to you. Take it with you to any and all appointments with your physicians. It can help identify patterns, as well as the best time for prescribed medications to be taken.
I hope this is helpful to you, and I wish you good luck.
