4. Surgery
Individuals that undergo surgical procedures may experience a severe impact on the body from the experience. Invasive surgical procedures and operations take a considerable toll on the body’s nervous system. As a result of the stress on the body induced by invasive surgery, the individual may find that they start to develop other signs of stress, such as ridging in the fingernails.
If you are to undergo any surgical procedure, check your fingernails before you go into the theater for any signs of ridging. If they’re smooth before the surgery, and then you discover ridging afterward, then it’s a chance that the stress of the operation started the ridging process.
In the recovery process, after the surgery, the physician may require you to take numerous drugs to recover from the effects of the operation. These drugs may also harm your physiology producing side effects such as ridging of the fingernails.
