I'm a bit worried about getting accurate readings from my oximeter. Does it matter which finger I use to check my oxygen levels and heart rate? I've heard different things and just want to make sure I'm doing it right.

I've been having shortness of breath for about a week now, and it seems to be getting worse every day. I saw a physician last week who thought it might be related to acidity, so I took medication for that, but it hasn't really helped my breathing at all. It gets particularly bad at night, although once I'm asleep, it's not an issue. I've noticed that as I become more aware of my breathing, the problem seems to intensify. I've got a bit of a cough in my throat and occasionally my nose gets blocked, which only adds to the difficulty. I end up having to breathe through my mouth and yawn a lot just to feel like I'm getting enough air. Do you have any idea what might be going on?
Since the medication for acidity hasn't helped, I recommend revisiting your doctor to reassess the cause. Given that the symptoms are persisting and worsening, further investigation is important to rule out conditions like asthma, allergies, or heartlung problems. Track your symptoms: Keeping a diary of your symptoms (when they occur, their severity, any triggers) can be helpful for your doctor to get a clearer picture. Consider seeing a specialist: If your physician is uncertain, you might want to see a pulmonologist (lung specialist) or an ENT specialist (for sinus or throat issues).

I'm a bit confused right now. I recently had a pretty bad asthma attack, and my doctor switched me to this duolin inhaler. Before that, I was using the Rotahaler, mainly because it was cheaper. I'm trying to figure out if the duolin inhaler is actually better for me or if I can just go back to using the Rotahaler like before. Any advice on what I should do?
Duolin inhaler, containing a combination of Levosalbutamol and Ipratropium, is generally considered more effective than Rotahaler (containing only Levosalbutamol) for managing severe asthma symptoms, as it provides both bronchodilation and anti-inflammatory effects, so it's recommended to continue with Duolin inhaler as advised by your doctor.
