I felt the same way, however I had a blood test taken where my uric acid level was 9.5 mg. Shortly after, I had an attack that lasted weeks. I was taking baking soda daily, cherry extract, tried some ACV, fish oil, vitamin C, etc. Nothing helped the pain go away fully until I received a prescription for indomethacin from my doctor about five weeks after the pain first started.
I took another blood test after having done all that, and my uric acid level was 9.2 mg. The reality is that even with baking soda, diet changes, exercise, etc, it is likely going to take allopurinol to get your uric acid level to be around 5 mg.
A book I read said that diet affects the uric acid level by 1 or 2 mg at most; a strict low purine diet isn't very practical in the long term as well.
In the end you should find what works for you. However I will say that it is beyond question that it is better to take a safe medication such as allopurinol and have your uric acid level in control than to NOT take allopurinol and have hyperuricemia untreated.
Finally, remember that you can always try to reduce the dosage of allopurinol if your uric acid levels are stabalized between 5 or 6.. just be careful that doing so doesn't raise the level back up above 6.
Good luck and keep us posted!
