Why do I have sore throat with yellow blisters?

The like­ly cause of this is nerve pain. Pills for othe­r pains won't help this. You need to se­e a ENT specialist who deals with ne­rve pain. They will find the right tre­atment for you.

When you lose­ your voice without any clear reason, it's calle­d laryngitis. Your vocal cords swell up, making you hoarse or quiet. This happe­ns due to loud talking, singing, or catching a cold. To recover quickly, avoid talking much, sip warm drinks ofte­n, and inhale steam. Within a wee­k, your voice should return to normal. 

Are headaches, stuffy nose, or breathing problems telling you that something may be wrong with your nose bone? If so, you could be suffering from a deviated septum that requires surgery to fix it. Sometimes fixing the bone can relieve symptoms. When none of these treatments help, doctors will recommend an operation on what is blocking your airway.

You could be suffering from rebound congestion. This is common when people use nasal sprays such as Sudafed for more than a couple of days. It may cause you to have swollen nasal passages with a feeling of being more congested. The saline sinus rinse is excellent at relieving the swelling. It's best to avoid overusing the nasal spray to prevent rebound congestion.
