I've been feeling kind of worried since yesterday. I was spray painting my bathroom cabinet for around 5 to 10 minutes, and I didn't use a mask. About 20 minutes later, I started feeling short of breath. Today, I'm still experiencing some shortness of breath, though not as intense as before, and there's a bit of coughing. A friend gave me some cough drops which helped a bit, but I'm concerned if I should just wait it out a few more days or if it's necessary to head to the hospital. What do you think?

Its possible that inhaling the spray paint fumes irritated your airways, causing shortness of breath and coughing. If your symptoms are improving, rest, stay hydrated, and avoid irritants. However, if you feel worsening shortness of breath, chest tightness, or persistent discomfort, its best to visit a hospital for evaluation.
