I had 2 chest x-ray days apart and blood test x-rays are clear they listen sound clear they found nothing i have tickle in throat with little cough?

Question?: I presume you are asking for a diagnosis of the cause of tickle and cough. The chest X-rays & exam of the lungs are normal, as expected, since the problem is likely in your throat. Did anyone check a throat swab? Have you tried warm salt/sugar water gargles? If symptoms persist, see an ENT, but most of the time, it's viral or allergic causes that lead to these symptoms & it goes away on its own.
