I'm dealing with this twitching on my left index finger that started a couple of days ago. It's just that one finger and it only lasts a few minutes, but it keeps happening. I'm kind of worried about what could be causing it and wondering if it's something serious. Is there a way to sort this out on my own, or do I need to see a doctor? Any insights would be really helpful.

The twitching in your left index finger could be due to minor causes such as fatigue, caffeine or nicotine consumption, nutrient deficiencies (magnesium, potassium, or calcium), or temporary nerve irritation, but in rare cases, it could be an early sign of a neurological condition like benign fasciculation syndrome, peripheral neuropathy, or amyotrophic lateral sclerosis (ALS).

Answered by 1 Apollo Doctors

My vision has been blurry and I've had this terrible headache that won't go away. Sometimes my speech slurs and I feel a bit out of it like I might pass out. Could this be because blood flow to the nerves in my brain is blocked? Would I need surgery for this?

Common causes of blurry vision and headaches are migraines, eyestrain, and other correctable vision issues. Examples of emergency causes include a stroke, dangerously low blood sugar, traumatic brain injury, and carbon monoxide poisoning
