Nurse Highlights Six Warning Signs of Acute Limb Ischemia
Thai nurse Ben-O RN shared six critical warning signs of acute limb ischemia on TikTok, citing a recent Lampang Hospital case where timely advanced surgery saved a patient's leg. High-risk groups include those over 40, diabetics, smokers, and people with heart disease or cancer. Amputation risk jumps from 6-8% within 12 hours to 20% after 24 hours without treatment.
Check six warning signs before losing a leg forever due to acute limb ischemia — who is at higher risk? Knowing early means survival. On November 13, 2026, TikTok user @Ben-O RN posted a clip sharing six warning signs of potential leg loss from acute limb ischemia, stating: "Six signs of leg loss risk if you know late, go to hospital late." This case had just undergone surgery a few days earlier at Lampang Hospital for critical acute limb ischemia. The patient survived thanks to advanced surgical technology; the medical team successfully dissolved and suctioned out the clot in time. If you have this condition and seek treatment late within 12 hours, the chance of losing the leg is 6-8%. If treatment is delayed 12-24 hours, the chance rises to 12%. If delayed more than 24 hours, the chance of amputation reaches 20%. People aged 40+, diabetics, those with hypertension, heart disease, daily smokers, or cancer patients face higher risk. Observe your own legs for these six symptoms: 1. Severe sudden pain even while resting. 2. Skin on the leg or foot paler than usual. 3. No palpable pulse on the top of the foot when pressing with fingers, or very weak. 4. Leg feels colder than other body parts. 5. Numbness or sensation like needles pricking. 6. Cannot move the leg at all. All these indicate acute limb ischemia. Detect early, treat in time to preserve quality of life.
