Doctor, I am male of 63 years with 76 kgs of weight, take Cilakar T, despite Uric acid level within the range at 5.7, yet left hand palm joints and left leg finger joints pain, what you think is the cause?

Hello Doctor, I am 59 yrs old, 90 kgs, height 6'1", a pure vegetarian. Mine is basically a sitting job. Last July, while doing a routine check up, I found out that my Uric Acid had shot up to 7.60. In fact, my toenails had started coming off. My doctor then advised me to take Febutaz40 everyday for 3 months after which Uric Acid came down to 4.30. He then asked me to stop for 1 month and it again shot up to 7.50. He has now asked me to take 1 tablet every alternate day, now my Uric Acid count is 5.70. For the past few days, I have been experiencing swelling and pain in my feet around the ankles as well as in the toes and fingers. Sometimes it is a tingling pain. I have completed 3 months of Vitamin B12 ( Meganeuron OD Plus ) which now under my Doctors instructions I have stopped. I am also taking Vit D for the past 3 months and supposed to take for another 3 months. My Question is : Should I take Febutaz 40 everyday for Uric Acid or continue taking alternate day, as is now ? And what could the possible reason for this pain in the feet and the toes and fingers ? Should I continue with my Vit B12 medicine ? Last July, my HbA1c was 6.30 which I brought it down to 5.80 by changing my diet and walking exercise. I had stopped sugar intake totally for 6 months after which my HbA1c was down to 5.80. Now I have started on sugar intake but very limited quantity and that too once-twice a week. Now my HbA1c is 6.10. Is it okay or should I stop sugar intake totally ? Just for information during the past 10 months, my FBS is between 98 to 108 and PPBS is between 110 to 140. I am not taking any medicine for sugar control. My cholesterol is between 140 to 180. Could you please revert back to all my queries ? Thank you
