My daughter is really struggling and can't sing properly, because she feels her throats blocked and she's loads of 'gunk'. Her voice coming out squeaky with no power. Had tonsils and adenoids out before Xmas but seems worse now . Trying everything, nasal sprays, antu-inflamatory, antihistamines, sudafed mucus tabs, inhalers, steaming etc. Just bought a nebuliser to try saline breathing. Currently trying lemon and ginger tea, and have bought pineapple juice ...not getting anywhere, she says its still there, and she has an audition next week. Shes gutted to say the least. She playing the role of Dorothy in OZ in June, so she has a good powerful voice usually . Please help !
