I am a 24-year-old female with no high cholesterol and no pre-existing conditions.
I had a dull ache in my right knee, but when I tried to walk it out like I normally do, everything below my right knee went numb and there was a sharp pain in my right hip.
When I tried to elevate my leg, my right leg became taut, with varying numbness and dull pain, and then I felt my right arm start to go taut and numb from the shoulder, spreading to my fingers.
I have no chest pain, I've had pain in the middle of my back today, my speech is fine, and I am coherent.  This has been going on for 20 minutes.
Please, what is happening and do I need to go to the hospital?
