<s>[INST] Hi, I recently fell of a horse and as I landed I got trod on by the horse on my inner upper right thigh. I first had lots of pain and I could not walk on it and every time I moved it I was in loads and loads of pain I then put some ice on it and it was better but it has now been 3 days and I still have a dull ache and difficulty walking and straightening my leg and it feels very stiff. However there has been no bruising at all but there was sweing... What have I done? Thanks. [/INST] Hello, As this fall has landed in the muscle injury. Straightening the knee will be difficult due to excessive muscle action. You need to wait for a week or so and till then continue icing to reduce pain but also use hot water fermentation to relax the muscles too. Post 7-10 days you can start slow and low-intensity static qua Chat Doctor.  This should help regain the strength in the muscles and allow the knee to be flexible. Trying hot relax and contract-relax techniques will help improve the knee range of motion too. Hope I have answered your query. Let me know if I can assist you further. Jay In </s>
