My 20 yr old son got punched in the face 3 years ago. He has had trouble with his sinuses ever since. His nose is always clogged and he has trouble swallowing. He saw specialists, had deviated septum surgery, has been taking acid meds, stopped most dairy, nasal spray..nothing works. right now he can barely swallow and has not eaten all day for fear of choking. We are hoping to get him an MRI FINALLY within 2 weeks.Question; Is there any temporary relief for thick post nasal drip, swallowing??
