Hello , My husband has had some hoarseness and a feeling like something is lodge in his throat, Larynx area. He initially thought it was a thyroid problem but IU ruled it out and suggested a Ent dr. Just some facts; he's been on hep c TX x's 2 with interferon etc and w/the most recent being harvoni, he's diabetic and has sleep apnea but hasn't got his machine yet in addition to snoring and sleeping with his mouth open. Just looking for some feedback. Thanks
