In june2018 I had chicken pox. After one month I got severe pain in my both knees. Till now its continuing. Doctors advised me to check uric acid level which is high. Uric acid result is 8.30 mg/dl (normal range is 3.5-7.2). I took zyloric tablet. After completing 10 days course my uric acid level came down to 4.30 mg/dl. But after discontinuing tablet uric acid level once again gone up. Kindly advise.
