Persistent tenderness in the heel.

It has been over 4 months that i've been carrying this pain on my left heel. The first orthopedic i consulted diagnosed it as retrocalcaneal bursitis and prescribed ice pack along with Chymoral forte, and a pain killer. He suggested to have ultrasound therapy for 3 days. Even after the Ultrasound and medication there was very little relief. In fact, by being conscious of the pain, my walking posture changed and i developed pain in my shin. I consulted another orthopedic (since i couldn't get to meet the earlier doc) and he diagnosed this as insertional tendonitis and prescribed T-heal for 1 month and a pain killer when required. He also gave me a sheet with exercises to strengthen my Achilles tendon. Also, suggested to use silicon pads in my shoes, which i did. It's been over a month since, and though the pain is less severe, i am yet to recover completely. Meanwhile, i got the Uric Acid test done and it returned 6.2. Am i having some chronic condition?
