Welcome to HealthcareMagic forum.
is followed by a process of inflammation which can last for few days to weeks. Difficult movements, pain and other swelling are typical of ongoing inflammation. This would gradually decline and resolve in a few days from now. However I am worried if you sustained a serious injury like a fracture
or torn ligaments/menisci where recovery period would be prolonged.
You need to continue icing and limb elevation. In addition over the counter anti-inflammatory drugs such as aspirin
taken twice a day after food should bring you more relief than currently. Whenever feasible, I also recommend you visit an orthopedic nearby for careful examination. X-rays/scans are entailed to rule out a serious concern.
Hope this answers your query.
