PatriciaRN does address the bruising symptoms as a possible side effect of some of the medications you are taking. One in particular, the Humira, has a "warning" in the list of side effects. This can cause a serious side effect of affecting your blood and causing your platelets to become too low. This causes unusual bruising. If it continues, it could seriously affect your health, causing bleeding elsewhere in your body.
You need to report this symptom to your doctor right away, and voice your concern about the possible side effect from Humira. Your doctor will be able to do a blood test to see if this is the case.
