Experiencing low back pain, buttock discomfort, and a sharp pinching sensation during the 35th week of pregnancy is common. It can be attributed to various factors such as hormonal changes, weight gain, pressure on nerves due to the growing baby, or even pelvic misalignment. To alleviate these symptoms, try practicing good posture, engaging in gentle exercises like prenatal yoga or swimming, using heat or cold packs on affected areas for relief. Additionally, consult your healthcare provider for further evaluation and guidance specific to your situation.
