So sorry to hear your wife is dealing with this- it's good that she went for some blood work as that will give you more answers than anyone here can. When does she get her blood work back? There are many conditions that you will see bruising and itching accompany, so it's best to have the doctor narrow them down with testing- some are minor and some are more serious. It's hard to wait for the test results, but that's the best thing to do at this point- let us know how she is!
