Symptoms of endometriosis-related pain may include:

dysmenorrhea (64%) – painful, sometimes disabling cramps during the menstrual period; pain may get worse over time (progressive pain), also lower back pains linked to the pelvis
chronic pelvic pain – typically accompanied by lower back pain or abdominal pain
dyspareunia – painful sexual intercourse
dysuria – urinary urgency, frequency, and sometimes painful voiding
mittelschmerz – pain associated with ovulation
bodily movement pain – present during exercise, standing, or walkingCompared with patients with superficial endometriosis, those with deep disease appear to be more likely to report shooting rectal pain and a sense of their insides being pulled down. Individual pain areas and pain intensity appear to be unrelated to the surgical diagnosis, and the area of pain unrelated to the area of endometriosis.There are multiple causes of pain. Endometriosis lesions react to hormonal stimulation and may "bleed" at the time of menstruation. The blood accumulates locally if it is not cleared shortly by the immune, circulatory, and lymphatic system. This may further lead to swelling, which triggers inflammation with the activation of cytokines, which results in pain. Another source of pain is the organ dislocation that arises from adhesion binding internal organs to each other. The ovaries, the uterus, the oviducts, the peritoneum, and the bladder can be bound together.
Brolucizumab (sold, depending on part of the world, under trade names Beovu or Vsiqq), is a humanized single-chain antibody fragment for the treatment of neovascular (wet) age-related macular degeneration (AMD).The most common side effects are reduced visual acuity, cataract (clouding of the lens in the eye), conjunctival haemorrhage (bleeding at the front of the eye) and vitreous floaters (spots in the vision). The most serious side effects are blindness, endophthalmitis (an infection inside the eye), retinal artery occlusion (blockage of the artery in the retina) and retinal detachment (separation of the retina from the back of the eye).Brolucizumab was designed to attach to and block a substance called vascular endothelial growth factor A (VEGF-A). VEGF-A is a protein that makes blood vessels grow and leak fluid and blood, damaging the macula. By blocking VEGF-A, brolucizumab reduces the growth of the blood vessels and controls the leakage and swelling. History
This drug was developed by ESBATech (discovery to phase 2a), Alcon Laboratories (phase 2b), and Novartis (phase 3).Brolucizumab is U.S. Food and Drug Administration (FDA) approved in ophthalmology as Beovu.Brolucizumab successfully completed phase III development in wet age-related macular degeneration (AMD) meeting the primary efficacy endpoint of non-inferiority to aflibercept in mean change in best corrected visual acuity (BCVA) from baseline to week 48.
