Panicking and worried. Is this a viral infection?

Hi. Today I woke up with my throat feeling weird as I feel like I have too much mucus getting more worst for me. I have post nasal-drip and been taking my medicine everyday, twice in one day for morning and before bed to help me reduce the symptoms but it doesn't seem to be working as effectively. This is my 10th day taking this as I have to use it for 14 days. I seen my doctor last month as he told me I had no viral infection but I have been getting headaches and feel like I need to cough. I have to constantly clear my throat as it also feels scratchy a lot too. Has anyone ever had post nasal drip symptoms before and know what I'm describing does match? I'm getting worried and been having panic attacks if it might be a viral infection.

it does sound like a infection you may need anti biotics go to the doctor and demand to get them as your health comes first

Thank you for responding. I’m a little concerned now since I know the dangerous virus is happening here now too and I feel like I might have a fever even though my head doesn’t feel warm but I have headaches that are irritating.
