I had TKR in May. Took Xarelto for only 1 month, ending June 18. Stopped cold turkey. Ever since, I get vivid dark brusing if I hit my lower arms (to wrist area). Even a heavey- duty bandaid, when pealed off gives this bruise. Doctor told me to stop taking fish oil, flax seed, etc. I am 72 years old. Since August, especially. Now November. Getting concerned. What blood tests? What causing? Never had bruising before.
