I am experiencing abdominal pain (severity: mild) , back pain (side: lower) , leg numbness and unable to bear weight. the following also describes me: lower abdominal pain. what should i do?

Dr. checks appendix: Lower abdominal discomfort can be from many things. For pain on the lower right, appendicitis is always a concern (pain usually worsens over time, with fever coming on). If one is constipated for several days, stool can back up all the way, and cause discomfort or pain. Gallstones, kidney stones, diverticulitis, etc., can also cause pain. One's primary care doctor or an ER doctor can check.
