My uric acid in blood shoots up to 7.9. I do not have the problem or gout or kidney stones. How to reduce it? I have already started to drink lemon water the whole day. I have attached the photographs. I have only knee pain, which is at the backside of the knee while climbing up and down stairs for the last two years. Also, my left leg thigh muscle has localized numbness for the past five years. Numbness did not hurt, but bothers sometime. Numbness is not heavy if i use nail on it or scratch on it, I sense it well. How to cure this numbness? Is this serious?
