Hi Sir/Madam 2 days back, my father aged 60 years developed Cold, cough with mucus and nasal congestion. I visited nearby General physician. Doctor prescribed Ebast-m, sporloc and Doxy-1 L tablets. Yesterday night after dinner, my father took his first dose of Doxy-1 L DR Forte tablet. At 3 AM, his left knee was locked and he was unable to walk. Now both of his knees are paining and he is unable to strech his legs. He is unable to fist his left hand. On the right hand, he is unable to bend one finger. Kindly let me know if this is due to the tablets that he took or a symptom of any disease. He is a diabetes patient. Kindly advise whom I can contact now. An orthopedic or GP or Neurologist. Thanks in advance.
