Depends...: Is this a chronic condition or something new? Is vision affected? Are the eyes painful? Any discharge? These other factors help us to determine how urgent an issue is.

Not too much: Blood shot eyes are usually caused by fatigue, dry eyes or allergies. Some would also classify subconjunctival hemorrhage as bloodshot. As long as the cause is known, there is usually no worry. If there is sudden onset without a cause, see an eye doctor.

With fingersticks: If the hands and fingers aren't clean and dry, home blood sugar readings may be inaccurate. Sugar on the fingers could end up falsely elevating blood sugar. A concomitant venous sample in lab could demonstrate a discrepancy. Also, the meter may be inaccurate. Eating before a fasting blood sugar may raise the blood sugar in someone with diabetes because it would not be fasting anymore.

Can l-arginine lower blood pressure & if so what is recommended dosage?

Possibly beneficial: In some people. Arginine is converted to nitric oxide, which has a relaxing effect on blood vessels & can thus reduce blood pressure somewhat. No standardized dose has been recommended. Be advised that arginine can also trigger or worsen viral infections like herpes. Discuss this supplement with your doc before taking it.

These days my wife is seeing flashes in one eye occasionally.?

See an eye doctor: Most of the time, flashes of light are related either to floaters (changes to the gel that fills the back of the eye), our less commonly migraines. If the flashes last for more than a day, or if there is a decrease in vision as well, see an eye doctor right away.
