Dr. Hanif warmly Welcomes you! Thanks for consulting me at virtual clinic. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns.   Some people have engorged vein naturally, some have due to Pharyngitis. And yes it may also be or may not be due to coughing.Asthmatics sometimes get engorged veins because they put more energy and effet and use muscle more forcibly to catch up the breath. So don t confuse and mingle the physical findings. I mean its a physicain or an ENT SPECIALIST who is trained to diagnose the lesion, signs and symptoms of diseases. YOUR EYES CAN T SEE IT, IF IT S NOT IN YOUR BRAIN so it may be misleading for you to diagnose and be worried. I suggest you to consult a physician to clearly do a physical examination and assessment. He will guide you in a better way then. Hope it helps. If you need further, detailed and quick assistance related to any health issues, feel free to ask me a question directly from my profile.
