Most : Most doctors would consider the phrase tingling "from the waist down" to mean tingling that starts from a belt-like line somewhere around the bellybutton and down into both lower limbs, and not affecting the trunk about the line, the face, or the upper limbs. This suggests that something is going on with the spinal cord, such as compression (such as a from a tumor) or inflammation (such as from transverse myelitis), or other problems. These problems are usually, but not always, associated with problems walking, with weakness in the lower limbs, or with problems controlling the bowels or the bladder. Numbness from the waist down requires careful neurological examination, and may require additional testing like mri, lumbar puncture, or electrodiagnostic testing to exclude serious disease. Symptoms that started recently or are getting worse require immediate attention. Symptoms that have been around for weeks or more, and are not getting worse, should be evaluated within a few weeks. High blood pressure and "fluid retention" are unlikely to cause numbness from the waist down, and hctz (hydrochlorothiazide) is unlikely to address the problem.
