Hello! By any chance has anyone had a sore throat for several weeks?! I have PCR negative, but it's been three weeks and it doesn't go away. In fact, in the late morning everything is fine, but as evening approaches, it starts to hurt, and by night the pain intensifies and so on until morning. They prescribed rovamicin and taniflu, from them there is no point, just like from regular rinses with furacilin, salt, baking soda. I think maybe ceftriaxone can be prescribed? The first time I was given it at the last week of pregnancy and after delivery, they say it can be effective and very good.
