<s>[INST] HI.. i m 18 years old.. i m 167cm tall and I weigh 57 kilos.. I twisted my ankle 3 days ago.. A doctor advised me to put a cast on and i did.. He said to put on a synthetic cast so that i can walk around.. is it safe to walk around with a synthetic cast? [/INST] Hello,Your symptoms seem to be related to a twisted ankle. I suggest using anti inflammatory medications such as Acetaminophen to relieve the symptoms. I also suggest to maintain the ankle immobilized with the cast. I recommend to rest and maintain the leg elevated to prevent further damage of the ankle.Hope I have answered your query. Let me know if I can assist you further.Regards,Dr. Dorina GurabardhiGeneral & Family Physician </s>
