Our 15-yr-old granddaughters fingers turn blue at different times for no apparent reason. No numbness, they just feel weak when it happens.  Its not when shes cold. What would cause such a thing? (Its not her feet...just fingers and part of her hands)We have asked the pediatrician and other doctors...even her sports therapist (shes a cheer-leader). Thanks
Hi, dairy have gone through your question. I can understand your concern. She may have cyanosis.  It may be due to malformations of some vessels or cardiac problems. You should consult physician for examination. If needed go for echocardiogram. Then start treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
