The claim "Arthritis comes from too much texting" is not true. Arthritis can be caused by many different factors causing joint pain, stiffness, and inflammation. Osteoarthritis is the most common arthritis which happens as you naturally age. Another cause of arthritis is developing gout where you have too much uric acid in your blood. Some other main causes are your immune system damaging your joints on accident, certain viral infections, and sometimes arthritis happens with no cause or trigger. Some things that can factor into getting arthritis is family history, obesity, smoking, or having an autoimmune disease. So although texting has no confirmed evidence that it causes arthritis it can lead to pain through repetitive strain worsening any existing arthritis.
