I'm 26 and I've been checking my oxygen levels with a pulse oximeter. It usually shows 95, but sometimes it drops to 93 before going back to 95. My pulse rate is around 92 most of the time. I don't have any other symptoms, but I'm wondering if this is normal. Should I be concerned, and which doctor should I see for this?

A pulse oximeter reading of 93-95% is generally within an acceptable range, though it can vary slightly depending on factors like positioning or movement. Since you dont have other symptoms, it's likely normal, but if you're concerned, consulting a general physician or a pulmonologist for a thorough evaluation would be a good idea.
