[|Human|] Hello yes last night I was feeling fine one minute, watching television and then I had sharp pains in my left  side of my chest that went through to the left side of my back.  I have been to the doctor this morning and he ran an ECG, which was all fine, and has advised that it sometimes can be muscular.  Any other ideas.  He has prescribed Nurofen and rest.
[|AI|]  HiT hank you for asking ChatDoctorI have gone through your query. As you have ruled out cardiac problems your problem is most likely muscle cramp. In such case you can continue European. Take a hot bath. Take milk and milk products for getting adequate calcium. If you regularly getting it D level in blood should be checked and if low, should take vitamin D supplement also. Hope this may help you. Let me know if you have any further query.
