Kindly don't self medicate. Nodosis contains Sodium bicarbonate which is an alkali used to relieve heartburn and indigestion caused due to hyperacidity (excessive stomach acid secretion) and to replenish bicarbonate ions in the body (in metabolic acidosis). It is also used in cases of excessive muscle spasms and in revival of unconscious patients (cardio-pulmonary resuscitation). Kindly follow the treatment directed to you by your treating doctor. If the problems persist or worsen visit the nephrologist at the earliest.
