welcome to Health care magic.
1.You have to see your GP and ask for a
lumbar spine AP/LAT x-ray get done, by seeing that if necessary a
MRI can be done to find the actual cause of pain (MRI helps to find the status of disc,
nerve , cord)
2.After that you may have to do some simple
back pain exercises on daily basis which will give relief from pain. You can do it initially - but you have to know the exact / how bad the condition is, some cases it will not help.
3.If there is any underlying medical condition, please make sure it is with in normal limits.
4.Before you treat, find out the cause for that.
Hope it helps you. Wish you a good health.
Anything to ask ? do not hesitate. Thank you.
