Hi, Welcome to Health care magic forum.
                  Quitting 
smoking may cause any symptoms but 
cold. Cold is usually caused by the 
allergy, viral infection, or esinofelia, etc. 
                  When not treated, may cause 
sinusitis, and effect the ear and hearing.  
                  I advise you to consult an E.N.T surgeon for diagnosis and treatment. you may need to have an M.R.I, for diagnosis.   
                  I usually prescribe to my patient with such symptoms 
ofloxacin, phenylefrine, citrizine, D.E.C,and multivitamins.   
                  Wishing for a quick and complete recovery. Thank you.
