Urgent care?

Hi all!

Keep meaning to ask this and forgetting - I know Presby in San Juan has an "urgent care" (but where???) on the weekdays, which they say is closed on Sunday. Other than that, are there any actual walk-in Urgent Care Centers open 24/7 (or at least, on Sundays!) in the Metro area? Minor stuff keeps happening and I hate only having the choice of waiting or mis-using emergency services.

It's down the street from the emergency room entrance. . Just past where the ambulance entrance is. . There is a ramp with an awning.  I think they let you park if u are going there but if not just park in the lot after Chili's.. It's about 1/2 block walk.
