Fingernails curving down!

I have been on Tamoxifen 14 months following mastectomy of left breast. Has anyone experienced curving of the fingernails? I only have this on my left hand! I have read that this may indicate underlying problems with heart, lungs etc but before I seek medical advice, has curving of the finger nails been indicated as a side effect of treatment for breast cancer. Many thanks.
