Tony08,

Either I don't know the location of Al-Sadd health center but want to help you, it might be helpful hopefully,
*1-

You're living at Al-Sadd...The Children emergency unit is situated there at the beginning of the street & you can recognize it with its high poles with red lights on it, these are the symbol of emergency units you can get some direction from there ...
*2-

A special pole with a few green lights is the symbol of the area health centers you can find those high poles if you're near the hospital.

*3-

A lots of tea stalls & shops are there in Al-Sadd, try to ask some people there about the health centre location :)
