My father has been suffering from sciatica for a long time.

He had difficulty walking due to sciatic nerve pain.

My grandmother has been suffering from neuralgia for many years.

He suffered from trigeminal neuralgia for a long time.

He was taken to the hospital with a fractured ischium.

I walk in the park every day.

I walk to school every day.

This problem is very difficult.

In order to overcome these difficulties, we all need to cooperate.

He is my best friend.
