Val.... I know how you feel and I'm not just saying that, these ass issues really do hit us where it hurts, it's like one step forward and three back all the time, it doesn't help when the area is already compromised as well, many times I've just wanted to give up, tears followed and depression all this and the never ending nagging pain make it almost impossible to enjoy life, but we carry on and live in hope that one day we'll be cured from this terrible torture.
I really hope things improve for you, the antibiotics will kick any infection into touch, it's best to take them as a precaution anyway...
