The study evaluates the effect of TENS (transcutaneous electrical nerve stimulation) as add-on treatment compared with conventional analgesic treatment in patients with endometriosis-related chronic pain. Patients with frequent pain and high pain intensity will be randomized to additional treatment with TENS or conventional treatment for 8 weeks to evaluate the acute effects of TENS treatment (n=40). Patients with endometriosis-related pain that is not frequent or without high pain intensity constitute an external control group. All patients in the study will receive TENS treatment for a total of 16 weeks, for evaluation of long-term effects of TENS treatment.
