<s>[INST] I have pain on my left side of my rib cage! I also have this tearing sensation on my right shoulder blade! No sweating! No nausea! I keep trying to twist my body to pop my left side of my body, but not no relief! I have been feeling very depressed and heavy! Crying a lot! I have had Acid Reflux and hospitalized for it years ago, but this is different! I just feel like my back needs to be popped or massaged! I am extremely tired! Been told I have Fibro! I have been taking St. John s Wort! No synthetic drugs! Have bad anxiety and panic! When I pull up my shoulder blades the tension leaves, but it is aggravating! Not sure what is going on - I am under a lot of stress and right now waiting on severe weather to pass through here all night long which isn t happening! Okay! Enough complaining! I just feel miserable and wonder if I will ever get out of this funk! [/INST] Hello, The pain in the left side of the rib cage can be due to a muscle spasm. Acid reflux is not related to the pain but can happen due to the pain killers that you might take to relieve the pain. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Praveen Tayal, Orthopaedic Surgeon </s>
