I have had severe back pain for the past week. I have  been off and on painkillers and muscle relaxers for these days. The doctor whom I consulted told me that exercise would correct my lower back pain issues. But the pain still persists. Can physiotherapy help for this? A friend of mine suggested to do the treatment from Physionow, a registered physiotherapy clinic in Mississauga where we live. I cannot sleep at night and wake constantly in a great deal of pain. Is there something else I need to get treated for a normal recovery?
