I have had a bladder infection for 3days now and its really bad, ive taken a number of cranberry tablets but it is still there. I havnt peed blood yet but iv got a really sore back and find it hard to walk. I started drinking orange juice yesterday and got the shakes really bad, i thought my body was going to have a fit, I just want it gone and really dont know what to do? is there something more worse with me?
