Hello, I live in Ireland, i recently visited Saudi arabia for a pilgrimage. After a few days upon arrival i got a severe cold and wet cough. I was drinking cold water at first but stopped due to nose congestion. i was also sleeping in AC daily. I was cleaning my nose daily as soon as it got congested. I was back in Ireland but still after 2 weeks my cold is not healed In fact I'm getting dark yellow mucus daily. I took paracetamol but I don't think it's effective as i might have an infection or bacterial infection. I don't know which medication I should take. I did research on my mucus color on the Internet, it said that i might have an infection. Should i take antibiotics as i have dark yellow mucus.
