I am having cold and cough from past 3 days and my left ribs got swollen so much and it's very painful. What needs to be done, please suggest. I have taken pain killer to get relief and it got relived for 5-6 hours after that again same pain. And also having lots of cough from 5 days. Also feel very lethargy every evening, don't feel like waking up from bed and very week as if no energy is remaining in the body. But the main concern is my swollen ribs and it's painful too
