Osteoarthritis
"Aspirin suits me best because I do not suffer from H-Pylori,otherwise,it may cause ulcers although Lansoprasol or Omepresol can prevent the stomach issues.
The reason that Aspirin is best is because it helps along with Vit C and Omega 3 to lubricate the joints which is essential for painless movement.
I sometimes inter-change with Ibuprofen which because it is coated lasts longer than Aspirin but I have no knowledge of Naproxen."
