5 days ago had L2-3 fusion and decompression. 3rd day after surgery started having unbearable buttocks and hamstring cramping spasms. Ended up in ER that night. Are these normal symptoms after this type surgery . I am desperate for answers and am scared to death because I walked out of hospital with no spasms or cramping and could walk. Now after 5 days after surgery I have severe cramping and spasms which have caused me to use a walker And cannot even sit on toilet or walk without help. Spasms are unbearable. Please help,, I need answers to why this is so painful. Incision site is ok just tender. The spasms are the main problem and are killing me. Please answer asap.
