I had hip replacement on 1/6, am taking lovenox injections. I had a catheter for one day. Now, I have trouble urinating, although I drink lots of water, have been told I do not have a bladder infection; I have to actually push out the urine and feel like I never can go - feels like there is inflammation. I also feel extremely fatigued; I was in the ER last evening; I have phlebitis and have been given antibiotic for this; the bladder is no better so far, though. Thank you for any info Sandra
