I have persistent sore throat since 4 months. I smoke daily and two times got bleed from mucus sputum. One got recently and another one back 1 year ago. General physician diagnosed my lungs and there are no such worsen symbol . He says me it's come from throat. I can't understand what is happening! One more thing to know can I use ciplox ear and eye drops in such condition like minor cut inside the ear due to earbuds which got top of cotton. Thank you in advance.
