I started to get a headache last night (mild to moderate) and persists today (actions like coughing make it hurt suddenly), a sore throat started during the night and persists today (mild to moderate), my right hand side gland in my neck is slightly swollen and hurts to the touch, I feel weak and unsteady walking, I would characterize my head as feeling very funny and dizzy . Pretty sure I have a common cold starting, but am a bit concerned about the weakness and dizziness.
