Hello dear, The symptoms as mentioned in your post can be attributed to musculo-skeletal injury secondary to the fall. Symptomatic relief can be obtained with ice application, intake of anti inflammatory preparations like Ibuprofen, & application of analgesic+muscle relaxant gel. Multivitamins & multimineral preparations also need to be added in your diet. If symptoms still persist, kindly consult an Orthopedician for proper clinical examination. Investigations like X ray & MRI of the lumbo sacral spine will be helpful in detecting any fracture, soft tissue injury or other pathological cause for the symptoms. Wishing you a good health. Take care.
