Hello dear
I understand your concern
Normal level of uric acid in the urine: 250 to 750 mg per 24 hours
Normal blood level of uric acid: 3.4-7.0 mg/dl
So I think it is blood level 6.4 which is normal in range.
And also compared to urine level it is normal.
So i do not think it is not elevated uric acid both in urine and blood.
There is no relation between high uric acid and
sinus problem.Gastric problem cause chest pain:
Take esmoprzole 30 minutes before meal.
Take syrup
mucaine.
Avoid spicy food and take
BRAT diet (Banana, rice, applesauce and toast)
For sinus problem:
Take antibiotic, antihistamine and anti congested.
Take anticongested nasal drop.
Hope this may help you
