<human>: sometimes but not always, when I strain a bit to go to the bathroom or move in an odd way I get a pretty good pain in my side like near the rib, it usually goes away pretty fast but almost feel like a severe cramp or charlie horse and it is painful, been happening for years and usually on the left side
<bot>: Hello, Some amount of cramps in left side of rib cage can be due to low salt and calcium in body. So I would suggest you to get serum B12 and vitamin D3 level in body checked. If there is low level than you need to take a little extra salt in diet. Also, you need to take tablet Pregabalin and Methylcobal daily. I hope these steps will be helpful for you. I would also recommend you to get ECG to make sure that everything is normal with your heart. Furthermore, I hope this answer will be useful for you. Let me know if there is any other followup questions. Thanks
