Thanks for your question on Health Care Magic. I can understand your situation and problem. By your history and description, possibility of musculoskeletal problem is more. Sudden movement can cause muscle spasm. And if you still continue that movement than bone will move against that spastic muscle. This process can produce certain sound. So possibility of this sound is more in your case.. You also feel tightness, this also favours musculoskeletal cause. So better to avoid movements causing pain. Avoid sudden movements. Start painkiller and muscle relaxant drugs.. Apply warm water pad on affected areas. Avoid heavyweight lifting and strenuous exercise. Get done calcium and vitamin d3 level as deficiency of these can cause similar symptoms. If deficiency then you need supplements. Don t worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
