What Causes Numbness And Weakness In Legs After Diagnosing Cyst?

5 weeks ago I began to have horrible pain in my female areas and my stomach. I got diagnosed with cysts and then, I was put on birth control pills, muscle relax. medicine and 3 motrin doses a day (4 at a time)... I now cannot walk, my left leg is spongy, numb and tingly and I cannot walk without crutches. My memory isnt working too well either. I'm onyl 20 yrs old and have no idea what's going on.
