I have high uric acid[=7.7]. I have pain below heel in both legs. I have taken Zyloric for 2 months and uric acid is reduced from 9 to 7.7. But no improvement in heel pain. Please guide. 

I an 70 year old. I have been taking one tablet of Zyloric for the last more than 10 years. My uric acid is up to 5. I have no other symptoms. Now for the last two months I have developed acute pain in my back radiating to calf muscles [left side]. My MRI report is normal excepting for age related changes. I am feeling better with medication. I want to reduce the intake of Zyloric now to alternate days. Should I do it.
