I have a constant left heel pain, and have a hard time walking or putting pressure on it.... as well as the vein on the back of my left leg is starting to pop out and I have pain and pressure there as well. These symptoms were bought upon suddenly and have persisted for almost 2 weeks, and is only affecting my left leg. What can I do to help alleviate the pain and discomfort, as well should I consider going to the hospital or making an appointment to see my doctor?
