Both of them are similar in more than one way. They can be pretty serious if not treated well, but for that, it is important to understand their difference and other information. Below are details on both of these reactions.

Corn vs Bunion

The main difference between Corn and a Bunion as both of them are caused by different circumstances. Corn can never be genetic as a result of deformity, while bunion can be caused due to defect in genes and due to some medical conditions. They also have different symptoms and treatments. Corn can be treated at home, but bunion, if not healed easily, can lead to surgeries.

It is a bump formed outside the toe. It is more common in older people, especially women. It is differentiated into three types:

  1. Congenital hallux valgus: these are genetic, present from birth.
  2. Juvenile or adolescent hallux valgus: this is common in teenagers.
  3. Tailor’s bunion: this type is not formed on the big toe but the picky little toe.

It can be caused due to many reasons, genetic, pressure on the foot, also have gradually over time. Risk factors of bunions are:

  • Family history of the same: if any of the ancestors has bunions, the child is likely to have inherited from them.
  • Foot injuries: some major injuries can also be a reason behind this.
  • Rheumatoid arthritis: This is a deformity that can lead to bunions.

It can be prevented by several methods, by wearing specially designed pads to provide a correct position to the foot, by changing the normal footwear, by wearing shoes specially designed for this, by taking pain relievers, by getting steroids in the form of injections, last but not least by getting the surgery done.
