I've been having this chest pain on my right side and in my back, and it's pretty constant. I've noticed it eases a bit when I use a hot water bottle, but then it returns after about five minutes. I tried taking Mobizox to help with the pain, but it seems to come back even more after like four hours. What could be causing this, and what should I do next?

Ecg and x-ray chest pa view is advised to the patient.
