I Have Had Shingles For Six Weeks Now. The Rash

I have had shingles for six weeks now. The rash is pretty well cleared up ...but.... I am still having lots of pain.. It was most in my right side just below the shoulder blade and under my right breast. But now I am having pains in the middle of my chest. Is this normal?? Wondering if I need a chest xray or could this pain be heart related???
