What causes pain in the big toe?

Pain in the big toe can be caused by various factors, mainly including: 1. Physiological factors: such as prolonged standing, walking, or wearing improperly fitting shoes and socks, leading to poor blood circulation or compression. 2. Trauma: injuries resulting from falls, impacts, or even fractures. 3. Hallux valgus: an abnormal foot structure where the big toe deviates outward, causing compression on the inner side. 4. Flat feet: excessive fatigue of the foot bones and joints, causing pain in the big toe. 5. Osteoarthritis: wear and tear of the joint cartilage, narrowing of the joint space, leading to pain. 6. Gout: accumulation of uric acid in the joints causing an inflammatory response. 7. Paronychia: inflammation of the tissue around the nail, presenting as localized redness, swelling, heat, and pain. The causes of big toe pain are diverse and require evaluation and treatment based on the specific situation.
