deep vein thrombosis
"Doc put me on this after finding a small blood clot in calf after TKR. First month was not bad but after that, my upper stomach started to hurt off & on all day, every day; migraine headaches every night; insomnia every night and horrible itching at site of incision; bleeding hemorrhoids also. Had a Doppler taken after 2 months and it did not find any clots.  Dr took me off of Xarelto cold turkey.  Very frightening because I was told you should be weaned off of it but doc seemed to be ok with immediately stopping.  It has been 4  days since I stopped and all the above symptoms went away, thank goodness."
