Day 3 of covid

Today is Saturday 07/19/25 it started on Wednesday late night into Thursday am I went to the doctor Thursday around 8am with major lower back pain, leg pain, feet pain, slight headache and small cough that's dry almost nothing comes up and when it does it's just clear and maybe a slight yellow but no green and mainly clear and small fever

Day 2 back pain wasn't as bad but the body pain did spread more around and head ache got worse but no fever

Day 3 I feel almost normal but my cough is a little more noticeable but clear phlegm, headaches not as strong but comes and goes randomly, body ache is better but still there Idk what to do I go on vacation starting Tuesday the doctor told me I should be fine by Monday and won't be contagious on Tuesday, I just want this to be done with plus today I feel slightly confused but idk if that's from the headaches plz help guys I did try to get antiviral but was denied because I'm only 26 which is stupid they only gave me prednisone
