Feel like a pressure headache. Guide.

Hi, I possibly had Covid 1 month ago . It's been 20 days I have been feeling better ( saying possibly because symptoms were mild except for throat pain which was bit severe.Rapid antigen showed positive but RTPCR came negative ) I mainly took Antibiotics for throat and Paracetamol for fever. Now I have mild headache from today on the both side of my head. It feels like a pressure headache with pointed pain sometimes. It got me concerned for all sorts of things. I have anxiety disorder and get extremely worried about health even with slightest sensation in body.I take paroxetine 12.5 mg daily for the past 3 years. Now I am concerned about about this headache. There is no other symptom. But all sort of fear comes to mind, including black fungus or any other serious problem. I am leaning towards doing a test even after 1 day. Please guide.
