Another Chicago Bulls’ player is having medical problems. This time it’s forward Tyson Chandler battling chronic fatigue:

Tyson Chandler’s annoyance, frustration and concern over his ongoing battle with fatigue will lead him back to the doctor’s office, possibly Thursday, the fifth-year Bull said Monday.

Chandler said doctors believe his symptoms are linked to a hiatal hernia, which they diagnosed last month. Nevertheless, he will undergo tests to rule out a problem with his lungs, he added.

After being examined by a doctor Saturday, his medication was doubled, Chandler said. His medicines amount to four pills in the morning and again in the evening, except on game nights when he skips his dosages to minimize potential side effects.

The 23-year-old is unnerved by the need for so much medicine.
