Final answer:
Lower back pain on the right side can be caused by muscle strain, disc damage, or other medical conditions. Improper lifting techniques are a common cause of back injuries. Pregnant women often experience back pain due to the additional strain from carrying extra weight.
Step-by-step explanation:
Lower back pain on the right side can be due to various reasons such as muscle strain, a herniated disc, or other conditions like appendicitis or urinary tract infections (UTIs). Lifting heavy objects improperly can place excessive strain on the back muscles and spine, potentially causing muscle strain or damaging discs and vertebrae. It's important to lift objects with your legs rather than your back to avoid these injuries. In pregnancy, back strain is common due to the extra weight and changes in posture. Remember, if you experience persistent or severe back pain, it is crucial to consult with healthcare professionals for a proper diagnosis.
