Power steering extremely tight when initially started. Why? on 1998 Mercury Grand Marquis

98 gr Marquis when initially started it is hard to steer. Very tight unlike normal. After a bit it loosens up. What could cause? I just had maintenance done an oil chafe with all fluids checked. I'm stumped!

Power steering pump could be failing and may need replaced or the filter may be clogging up.
