### output:

Hi, as you mentioned the brief history of you that you had a fall on your hip region, there is a possibility of an injury to the soft tissue and if the impact is big it may lead to bony injury.since you said the MRI, x-ray and CT are normal which area did you exposed for the diagnosis is important. Taking an MRI of the lumbar spine will provide some input as well. If any soft tissue damage or any listless is happened. Since you fell on your hip region there may be a chance that due to inflammation of the muscles of hip the nerve is getting pinch and later on the symptoms may arise in the form of sensory or motor. I will advise to some small lower limb exercises which will help maintain the normal property of muscle maintained and then the pain will ease if there is pinched nerve dude to muscle inflammation. Also to advice that if you haven't taken the MRI of the lumbar spine you should go for one since you mentioned that while coughing or sneezing your symptoms are increasing. With the grace of God I wish you a speedy recovery
