Hello! I may be being a tad over cautious here, but last night I fell on the stairs; my upper right thigh had a direct impact with the edge of a stair. It hurt however I slept it off- today was okay, but about 12 hours ago my thigh began to throb. I can no longer bend my leg without pain. I can stand on the afflicted leg, but attempting to crouch on it is impossible, as is crossing my legs and I m getting severe pain using it to climb the stairs. I do not have any bruises or swelling, but the pain I m having is unusual for a simple knock to the thigh. Could you give me some advice? Thank you!
Thanks for your question on Chat Doctor. I can understand your concern. It is quite possible that you might be having hair line feature that is causing this worsening pain and symptoms after 12 hours of fall. So in my opinion, you should first get done x-ray of affected thigh to rule out hairline fracture. If x-ray is normal then no need to worry about this. Sometimes inflammation in the injured muscle can cause worsening of symptoms after 6-10 hours. So avoid movements especially weight-bearing. Apply warm water pad on affected areas. Take painkiller and anti-inflammatory Chat Doctor.  Take proper bed rest with minimal mobilization. Don't worry, you will be alright with all these in 1-2 weeks. But better to first get done x-ray to rule out hairline fracture. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
