### input:
Hi, recently tripped but didn t fall. I skid on the carpet wearing sandals and pitched forward. I had pain when I did this but it went away until the next day when I was getting up from the toilet to put my pants on. WHAM, my side of my knee hurts bad. It hurts bad when I stand and my only relief is to sit down and perhaps lean to the right. At night I can t lay on the opposite side as it hurts so I lay on the painful knee side and I fall asleep? What could this be?

### output:

Here there are a couple of possibilities it may be strained on soft tissue, or it can be damage in cartilage (in side) of joint due to weight-bearing along with twist movement, pain can also be due to ligament strain on lateral ligament strain or ACL, PCL ligament strain.However the conformation can be done only by specialist examination. So I suggest visiting orthopedic or physiotherapist, and they will do different physical test to check on your knee problem. Here doctor may ask to do MRI of knee for further conformation. Treatment will be planed as per the examination and report. Here if there is major damage to knee ligament or cartilage then arthroscopy correction may be needed. For any minor to average issues doctor will suggest taking physiotherapy treatment along with few anti-inflammatory and cartilage healing medication. You should also take proper knee strengthening exercise program to follow gradually on your own from physio. You can also use hot and cold pack frequently at home for some more relief as well can also use crew bandage on your knee for stability while walking in your daily activity. Follow all above suggestion and you will be fine. Take care.
