[|Human|] i have had an allergy like symptoms for a while, my nose is constantly clogged. yesterday i caught a cold from my brother i think, and today when i woke up, my nose was jammed up, as i blew into it, bright red blood was all over the mucus, it lasted till the late afternoon. my throat feels kind of sensitive somehow, should i worry?
[|AI|]  Hi, cold is a viral infection that spreads through aerosol means by air. Yes you are right what you caught from cold may be by your brothers cold. It is impossible for humans to get immune to this cold because every time different type virus causes infection. The good thing is it affects to nose and throat mainly by running nose, congestion, blocked nose, throat pain, cough which mostly subsides by itself. If not then u can take symptomatic treatment available OTC along with steam inhalation, saline nebulizer, avoid cold products and u will be alright.
