I'm 19, and short at 5'6, I'm a guy, I have this discomfort in my left knee above it. It sometimes pulsates and when I poke really hard and prod at it, I feel like squishy stuff moving around and I don't feel that above my other knee. I have anxiety. But I'm so scared that this is osteosarcoma.....
Hi Arkanian,
There are MANY ligaments in/around your knee. They can also feel "squishy."
Are you having pains that wake you up at night? Do you walk with a limp? These are some possible signs of osteosarcoma. Many times it isn't found until the bone fractures.
How long have you had these pains? At 19, you are well past the age when this type of cancer usually occurs - during a growth spurt.
Without knowing exactly what you're describing I can't be more specific. Your doctor will take an x-ray and, if anything is suspicious, a biopsy.
