Hi! I had this serious blockage on my right ear and visited an ENT, was told I needed ear syringing. I did an it cleared. but currently have slight fullness and speak as if under water or from my right nose. I am on some drugs like kambid 500, stugeron, actifed, cetin, vit C, Sinufed, etc. but am still having that muffled hearing and speaking as from a gun barrel. it is so inconveniencing and its making me more introverted and worried. I saw earpopper online. is it safe fir me to use it? I reside in Nigeria. thank you so much and I hope to her you soon. Arthur Uwagie.
