Botox shots aim to save limbs in rare Smoker's disease

This study tests whether injecting botulinum toxin (Botox) into the hands or feet can help people with Buerger's disease, a rare condition that blocks blood flow and causes severe pain. Eight adults with critical limb ischemia will receive a single injection session and be followed for 6 months. The main goal is to see if the procedure is feasible and safe, with secondary checks on pain and healing.
