Thromboxane Function in Women With Endometriosis

The goal of this clinical trial is to compare neurovascular regulation in women with endometriosis and healthy women. The main questions it aims to answer are: * Do women with endometriosis have greater blood pressure and pain responses to a stimulus than healthy women? * Do women with endometriosis have greater platelet activity than healthy women? Participants will take aspirin and/or placebo and will: * perform hand grip exercise and cold pressor tests * undergo iontophoresis and blood draw Researchers will compare women with and without endometriosis to see if there is a difference in neurovascular regulation.
