Crystals format and dissolve in a person with gout.
Excess uric acid crystalizes and it is our immune system that causes pain as it tries to isolate these crystals by covering them up with some coating. Once the crystals are coated they become "invisible" to the immune system and the pain stops. So far this explanation is just like at icuredmygout.org.
When the uric acid drops below some level, the body uncovers the crystals and starts to dissolve them to bring up the level of uric acid. This is where it gets interesting at goutpal.com: Apparently this ALSO causes pain because once again the immune system "sees" and attacks the crystals before they dissolve. This pain should go away if (1) all the crystals dissolve or (2) if the immune system coats the remaining crystals before they had a chance to dissolve, or (3) the level of uric acid goes back up above that threshold level and no more crystals need to dissolve and the immune system coats the remaining crystals. (If the uric acid goes above another threshold level, then that would lead to a new crystal deposits and new pain. So, as long as the uric acid fluctuates between these upper and lower threshold levels, you should not get gout attacks.)
I find this interesting because it could explain what has been happening to me. I got my first gout attack about 3 weeks ago by now. After a very painful period of about 5 days (treatment consisted of cortisone injection, colchicine, etc.) the pain subsided. I then started the baking soda treatment, following the procedure at icuredmygout.org. After a couple of days the pain returned and I couldn't figure out why because I drastically changed my diet and I didn't think the baking soda could make it worse. Now I think that it is possible that because of the baking soda I had a significant drop of uric acid, which led to an uncovering and dissolution of crystals, which led to the pain.
Have other people who started doing the baking soda treatment and who have stated that it helped them have also had these secondary periods of pain?
