chiropractor for sharp shooting pelvic pain and pressure when walking during the third trimester of pregnancy

Short answer

Sharp, shooting pelvic pain during the third trimester is most commonly associated with Symphysis Pubis Dysfunction (SPD) or Pelvic Girdle Pain (PGP). These conditions occur when the ligaments that typically keep your pelvic bones aligned become too relaxed or the joints move unevenly, often leading to a "lightning" sensation or heavy pressure during movement.

Most likely causes

• Symphysis Pubis Dysfunction (SPD): The hormone relaxin softens the ligaments at the front of the pelvis, causing the joint to become unstable or gap slightly.
• Pelvic Girdle Pain (PGP): Asymmetry in how the three joints of the pelvis move (the two SI joints in the back and the pubic symphysis in the front) causes localized or radiating pain.
• Round Ligament Strain: Sharp, jabbing sensations in the lower abdomen or groin triggered by sudden movements like walking or rolling over in bed.
• Fetal Positioning: As the baby "drops" or engages in the pelvis late in the third trimester, direct pressure on the pelvic floor and nerves can cause shooting pains.
• Sciatica: Compression of the sciatic nerve by the growing uterus or shifting pelvic bones, leading to shooting pains from the lower back through the buttocks and down the leg.
