Hello,
You snapped in the knee after you slipped while going down the stairs. You do not have any swelling or soreness, but pain whenever you try to stepdown. You are suggested to get clinically examined by an orthopedist or visit ER, get X-ray done to detect any
fracture, dislocation or hair-crack, it will be treated accordingly. You will have to get
MRI done to study in details on any ligament, tendon or muscle tear, etc. You will be treated accordingly.
Partial tears may heal by itself by rest, icing and keeping the knee elevated on a pillow when on bed and on a stool when sitting. Do not put pressure on the affected knee when required you can walk with the help of a walking stick. You can take NSAIDS,
naproxen, one SOS when needed. It will give relieve from pain.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
