Bollywood actor Salman Khan's recent public appearance at an event organised by Mumbai's Slum Rehabilitation Authority (SRA) has got some of his fans worried about his health.

In the videos that went viral on social media, netizens expressed their concern, saying the actor looked dull with noticeable weight loss and slower movements. Later, the actor on his official Instagram page posted pictures of himself with a caption, Aap logon ki tabiyat kaisi hai? ("How is everyone? How is your health?") was widely interpreted as a response to the speculation about his own well-being.

Previously, the actor had revealed being diagnosed with trigeminal neuralgia on Two Much with Kajol and Twinkle.

What is trigeminal neuralgia?

It is a condition that causes intense pain similar to an electric shock on one side of the face. The condition affects the trigeminal nerve that carries signals from the face to the brain nd can be long-lasting.

According to the Mayo Clinic, people diagnosed with trigeminal neuralgia may have short, mild episodes of pain at first. But the condition can get worse, causing longer periods of pain that happen more often. It's more common in women and people older than 50.

Experts list the following as the triggers that may set off the pain of trigeminal neuralgia:

  • Shaving.
  • Touching your face.
  • Eating.
  • Drinking.
  • Brushing your teeth.
  • Talking.
  • Putting on makeup.
  • A light breeze blowing over your face.
  • Smiling.
  • Washing your face.

How is it caused?

Pressure or damage to the trigeminal nerve causes trigeminal neuralgia. Under the classic condition, a blood vessel pushes on part of the trigeminal nerve root, which is the most common cause. In secondary trigeminal neuralgia, conditions like multiple sclerosis, a tumour, or arteriovenous malformation damage the nerve. However, in idiopathic trigeminal neuralgia, there's no clear cause for the pain.
