Hello dear, The symptoms as mentioned in your post can be attributed to musculo-skeletal injury. X ray of the hip joint can be done to rule out any pathological cause for the symptoms. The bruise & knot is due to accumulation of fluid & blood (hematoma) which will subside in due course of time. Symptomatic relief can be obtained by application of ice, analgesic & muscle relaxant gel, intake of analgesics like Diclofenac (to be taken after food) + Pantoprazole (to be taken 30 minutes before meals). You can include supplements of Calcium & Vitamin D in your diet which will help in strengthening of bones. Physiotherapy exercise will also be helpful. There is no need to worry, you will be fine. Till then, maintain adequate hydration & nutrition status, take proper rest and avoid stress. Wishing you a Good Health. Take care.
