<s>[INST] Hi Dr. Samuel,I would like to know what cause my right side lower back pain and cracking?  It has been going on for almost two years now.  Do I need to go see the doctor immediately or is there any stretching techniques I can do to fix it.  If i need to see the doctor what kind of doctors I should see.  Thank you [/INST] Hi,Low backache looks like a positional anomaly. The low back ache is a result of muscle spasm which in itself is a protective mechanism body develops so that the back avoids abnormal posture. For pain to go, it takes not only rest (on a comfortable bed) but also avoidance of particular positions (during work, rest or recreation).Avoid sleeping on sides and stomach in case you do. While on work don't sit in one position for more than an hour and take frequent stretch breaks. Do not bend forward to lift things up, bend the knees and hips for that. Also discontinue any strenuous activity or exercises for some time.Having said that, you might want to consult your orthopaedician for a detailed physical examination and appropriate investigations.For future query, you can directly approach me through my profile </s>
