Hi Doctor, My mother (58 yrs) is suffering from a pain in her lower back (left side). She describes this pain as being a constant one with occassionally electric shock type feeling. We visited a general physician who prescribed her Xerodol P (to be taken for 3 days) along with a medinine to sooth the nerves (to be taken for 30 days). She was fine for next 5 days, post which the pain has come back and painkillers are not helping. Please suggest. Thanks in advance.
