Pain in the inner thighs after sitting for some time or when straightening the legs is most commonly due to adductor muscle tightness or strain, especially with prolonged sitting, floor sitting, or sudden standing. It can also be related to hip stiffness, poor posture, or reduced flexibility, which makes the muscles painful when they are stretched after being in one position. the pain causing temporary difficulty in walking suggests muscle spasm rather than a joint problem. Avoid prolonged floor sitting or sitting with legs folded, and change positions frequently. If pain persists, worsens, or is associated with groin swelling, hip pain, or numbness, a clinical examination would be advisable.
