Hello Doctor I have a pain in my left chest and breast since yesterday. Even earlier, i have experienced this pain and i got a breast sonography done,results were normal And doctor said it was muscle pain only. I have also got ECG done, that too shows normal. Now again for the third time, I am experiencing this pain. I think it could be chest muscle again, I have 3 gels with me , which one should i apply to check if there is relief. - Infen Gel, AR5 Gel and Volitra . Thanks a lot
