A week ago, it started with a slight discomfort in my left knee. Two days later, I could walk without much pain, but stairs had to be done one at a time. Pain helped by taking Aleve. Icing the knee did not appear to help. Feeling around the kneecap, the painful area is above the kneecap. Occasionally, the knee feels unstable.
Hi, I understand your concern. From what you are describing, I think there is a problem with your knee ligaments as you feel your knee unstable. Apply analgesic cream locally. Take glucosamine supplement orally, apply glucosamine gel locally. Try to limit knee movements. If still no improvement, should consult further with orthopedic specialist and run further diagnostic tests. Wish fast recovery.  Chat Doctor.
