Welcome to SR. You should definitely get with a medical professional to take a look and diagnose your health situation. Like many things that aren't good for us, alcohol is very inflammatory and using it leaves our bodies in a state of toxic shock. When you stop, your body kicks into high gear in an effort to get back to equilibrium and sometimes the initial stages of detoxifying can look and feel worse than when you are using. Detox symptoms are many and varied. But please see a doc. They can give you things to help that process and make sure you are safe.
