When sitting in my recliner or desk chair for a couple of. hours i get a pain that runs down the back of my right leg to my ankle. what would cause this.?

Positional nerve: You may be experiencing sciatica. Sitting may be allowing the nerve from the back to be irritated. This can be caused by arthritis, bulging disc.

Possible sciatica: Sciatica is caused by irritation/pressure on nerve in buttocks that travels to feet. Try sitting differently to see if symptoms reduced. Orthopedic dr. Consult if no relief.
