Palpitations and anxiety. I was a child)

Palpitations but heart rate 96-98 sometimes goes more than that but usually stays in this range...my heartrate was always around 90 but in quarantine i feel like it has become forceful and i can constantly feel it beating...sometimes(intermittently) mild needle prick kind of pain at exact one point in chest thats around 5-6th rib left side but its mild not much.. I have anxiety problems too..and think too much..get afraid of little things and specially in this pandemic , afraid about a lot of things sitting at home all the time...developed nodules on hands and sole 3 months back for which i consulted dermatologist online who suggested me medication for erythema nodosum (took omnacortil during which i developed palpitations) and i have sometimg stretching pain on standing after long sitting in inguinal region...sometimes submandibular region and parotid region also feels different like not painful (friend had mumps 7mnths back but i had already developed when i was a child)
