Kaley Cuoco Reveals She Suffers 'Mommy Wrists' In Both Hands: 'Feeling Sorry For Myself'

Kaley Cuoco, who shares nearly four-month-old Matilda with Tom Pelphrey, is having one of those down days thanks to motherhood. Since welcoming her only child in March, the award-winning actress has been open about her parenting experience, revealing that it is not all roses.

In a recent social media update, the actress revealed that she appears to be suffering from a mom-related condition.

In two new Instagram Story snaps, Cuoco showed her hands are not in the best shape as they are being treated for "mommy's wrists." One of the images showed the movie star's hand looking swollen in a compression brace with her perfectly manicured nails painted a deep shade of red.

"The Flight Attendant" star wrote on the post, "They call it 'mommy's wrist,'" though she seemed shocked about the diagnosis as she added, "Are you kidding me?" She then dropped a second update — a mirror selfie showing her two hands in splints, indicating they were both affected. "Did I mention it's both hands?" she stated, adding an "Ouch" sticker.

Cuoco, who photographed herself in a well-lit bedroom, looked moody but explained why by writing, "Just me sulking feeling sorry for myself lol."

Mommy's wrists, also called Mommy's thumb, is a condition that commonly affects women's wrists, mainly pregnant women and mothers of youngsters. According to the American Society for Surgery For the Hand, the condition is scientifically referred to as "de Quervain's tenosynovitis or tendonitis" and causes discomfort in the thumb, which worsens whenever the thumb moves.

Although the cause of the condition remains unknown, it results from "irritation of the tendons that extend the thumb in their surrounding sheath at the wrist," and patients may notice a cyst, bump, or swelling in the affected area. 

Mommy's wrists can be diagnosed by physical examination, X-rays, or Finkelstein's test. Finkelstein's test involves a patient placing their thumb into their palm and wrapping their fingers around the thumb.  Afterward, the patient moves their wrist towards their small finger, reproducing their pain. The process has been proven to be quite painful.

Fortunately, surgery is never needed to treat the condition as patients recover with time. Hence, several non-surgical treatment options include wearing a splint, resting the hand, using anti-inflammatory medications, hand therapy, adjusting how the affected hand is used, and utilizing Corticosteroid injections.

Two months before Cuoco was diagnosed with Mommy's wrists, she opened up about having a bad mom day on her Instagram Story using a photo of herself carrying a bawling Matilda. She captured herself lounging in the sitting room of her home, wearing a gray T-shirt and a blue and yellow tartan pajama bottom while her baby was clad in a black long-sleeved onesie. 

The "8 Simple Rules" star looked worn out in the post, but Matilda was not so bothered as she kept on wailing. "Not every day is perfect!" Cuoco captioned the picture, adding a crying piglet sticker. In a following update displaying an endearing snap of a cute-looking Matilda, the "Charmed" actress clarified that some days were better than others.

The little one who rocked a two-piece ribbed pink outfit appeared in a better mood as she was not crying. A relieved Cuoco then declared on the post, "But most are!" adding multiple heart emojis.

Despite the Mommy Wrist diagnosis, Cuoco has been going pretty hard at her postpartum fitness routine, and it has certainly paid off in her toned physique.  She recently blessed her followers with a view of her enviable body via her Instagram Story, with a note indicating she had just concluded a Pilates session in her home gym. 

The "Growing Up Brady" star was surrounded by gym equipment in the picture and donned an all-black gym attire, including a sports bra that drew attention to her defined abs and leggings that flattered her hips.

She left her blonde hair tied into a messy bun but accessorized with a gold chain, a bracelet, and a tiny ring on her pinky. Adding a text overlay, she joked, "I got the Pilates bug again." 

The "Toothless" actress later uploaded a second selfie captioned "STRONG," where she flaunted her biceps and teased a view of her back. Fans were also able to see a closer view of her sweaty face.
