Gout
"I suffered debilitating Gout foot pain, due to my love for animal-based protein. With Allopurinol daily, I can eat those foods again...just in moderation now. I am a fit, lean 51-year-old Mountain Biker, who rides 3-4x a week. Side effects are nighttime itchy arms and back. I hate taking any meds - but Allopurinol is cheap and now part of my daily dosing. I also had to stop taking daily Aspirin(325mg) as it was amplifying my Uric Acid levels."
