My brother suggested another dr, that is, an upgraded X-ray. If there is nothing wrong with the bone, it is traumatic arthritis. This is caused by improper treatment after your previous injury, that is, you did not receive a good treatment plan or were not cured. Plus, I don't know much about my illness, so I use other irrelevant drugs at will. If your knee joint is still swollen, I suggest you go to a regular Chinese medicine hospital to see an orthopedic surgeon, take out the inflammatory fluid inside and put some anti-inflammatory drugs in it. Take Panax Notoginseng Wound Tablets orally again for about 10 days! Let your legs have a good rest for half a month. Less activity! Nothing else! Young man, diseases like yours are very common in our orthopedics department of traditional Chinese medicine! No problem! Now rest mainly! Of course, you should say that your bones should be fine! Western medicine can relieve pain, while Chinese medicine can cure the problem. China's history of thousands of years is not blown out!
