My mom received a joint replacement in her thumb about 2.5

Customer Question

Hi! My mom received a joint replacement in her thumb about 2.5 months ago. Today we noticed her index and middle fingers, the nails are growing curled down at the ends. Its only on those 2 nails. Is this possibly from her surgery or is there a different/underlying reason in which she needs to see her doctor? Everything is fine with the incision/healed up/very little scarring. Wore a cast (finger tips exposed) for 1st 6 weeks out of surgery, then a removable splint for 6...any ideas what is causing this?

There are a variety of reasons for fingernails curling under. If the ends of the nails are also enlarging, it may be a result of a lack of oxygen from COPD, asthma, or other respiratory disorder. It can also come from an injury (especially if only one or two nails are involved), from some vitamin and/or mineral deficiencies (especially D3, calcium), and also from inheritance. If her parents had curled nails, hers may be beginning to curl also. She would need to see her doctor for blood tests to determine if there are deficiencies that are causing the problem.

Kind regards,
