Hello doctor, i hear a crackling sound in my knees bones while sitting, standing, squatting simply put every time when i have to bend my knee and eve?

Joint laxity: 26y female describes "cracking" sound emanating from both knees with changes in range of motion. Pain & swelling is not referenced. Age, sex, and symptoms arouse concern for Hypermobility Syndrome, an often benign confition, which has genetic underpinnings, but which can predispose to development of several dysautonomic disorders and Fibromyalgia.
