North Cliff Hotel Dirty water source or spa tube Fort Bragg California

I have been visiting Fort Bragg with my boyfriend on 9/16-9/17, and staying in the North Cliff Hotel. Everything was nice until after we "enjoy" the spa in the hotel. On the next day of the spa, my skin got some red spots and also infection in my lady part. After talked to my boyfriend, he got some red spots on his belly after the spa too. We didn't go to swim or having contact to something special except for soaking in the spa of the hotel, so i suspect the water source and question if they have cleaned the spa tube before i moved in. I tried to call the hotel but the manager just don't call back.
