Thanks! I am going to have some x rays done on Monday.
Hello!
You should not wear heels and unstable footwear. Do not do weight bearing on the affected knee.
Apply ice packs and take anti-inflammatory medications such as ibuprofen or naproxen.
You should get some scans done and get yourself examined by an orthopedician.
I suspect a ligament tear, based on your symptoms.
After a proper diagnosis start treatment accordingly.
Take care!
