Pubis Symphysis Dysfunction
Symphysis Pubis Dysfunction, also known as SPD, is a common painful condition associated with pregnancy in which the ligaments responsible for the proper alignment of your pelvic bone become relaxed and stretchy. As a result, the symphysis pubis or the pelvic joint becomes unstable, causing moderate to severe pain along with certain other symptoms.
Pain in the pubic area and groin are the most common symptoms, though you may also notice:
Back pain, pain at the back of your pelvis or hip pain.
Pain, along with a grinding or clicking sensation in your pubic area.
Pain down the inside of your thighs or between your legs.
Pain that's made worse by parting your legs, walking, going up or down stairs or moving around in bed.
Pain that's worse at night and stops you from sleeping well. Getting up to go to the toilet in the middle of the night can be especially painful.
Most of the time, the relaxine hormone is the underlying cause of the dysfunciton. Trama may also be a valid cause as well as tension build up due to tension in the gluteal region.
