Yes. Find out about heavy metals as soon as possible. What you're describing sounds like an especially severe version of what a lot of people with heavy metal toxicity experience.
Your first dose may have come from you mother through the placenta while you were still in the womb (assuming she had heavy metal exposure while she was pregnant). All of your other exposures may have added to your woes, especially if your body is especially sensitive to the metals, or your natural chelators work poorly.
