This seems to be random. These are communities on the instance I'm logged into. AFAICT I'm not being blocked in these communities. I'm not even sure if mods *can *block someone from seeing a community. I'm guessing this has been asked before, but I couldn't find a thread on it.
In the winter, I spend more time with sinus infections than without. I feel like I've tried everything, but relief is temporary at best.
edit: Thanks for the tips everyone. Upvotes all around! Some of these suggestions I've tried, others are new to me. I'm going to give them all a shot. Looking forward to breathing again!
