I know it's so difficult when you have a medical condition. Hopefully losing weight will help some with inflammation. Does the neighbors smoke actually come into your apartment? If so, I wonder if an air filter would help. We got one of those when we had Forrest fire smoke in the house last year. We weren't able to get one until the fires were mostly gone but I'm ready for this year! Smoke is so awful! Hope you can find a way to get rid of it!
