HI , I'd really like to know if anyone else has this problem (and what it is that is causing it ).I have an acidic like urine (well it feels like acid )around the time of my period and a few other times durning the month but always at the begining of my period. A few weeks ago they tested and there was blood in my urine so they assumed that it was a bladder infection but the antibiotics they gave me didn't work. Now i'm set up for a ultra sound in a week and my period just started today ...hence the acid pee.. plus I've been tired and have had pains in my backand stomach .Honestly feel just mildly crappy but this has been going on for a while now and the doctor now seems to think it may be an abcess on my Ovaries or possibly the area where my Appendix where removed ..just 7 months ago ... so any info on what this could be would be great !
