Amy Schumer is on the mend following surgery.

Schumer, 44, stood proudly with a walker while at home Saturday in a snap shared with her millions of Instagram followers.  

The "Trainwreck" actress confessed on social media that she underwent back surgery and was expecting a "short recovery" process.

Schumer sported a pair of pink sweats with a red Catskill mountains sweatshirt and a pair of sturdy tennis shoes as she posed for a photo by a staircase.

"Since my surfing injury back in the day my L5 has been killing me," Schumer captioned the post.

"Today I got a laminectomy! It’s a short recovery and when I’m feeling better I will buy a bra!"

Hundreds of friends and fans cheered Schumer on, and sent well-wishes for speedy healing.

"Feel better soon my love," Kathy Hilton wrote, while country singer Elle King commented, "Surgery chic le freak."

Debra Messing wrote, "Oh s--t ….. heal fast," and Bethanny Frankel exclaimed, "OH NO."

Supermodel Helena Christensen sent a positive affirmation and told Schumer, "The Catskills has never looked better! Heal well and fast."

Schumer's back surgery comes months after the "Kinda Pregnant" star began using a new weight loss medication. 

Earlier this year, Schumer praised the effects of Mounjaro (also known as tirzepatide) after experiencing the negative effects of Ozempic.

"I wanted to share and keep it 100 with you, that years ago – and yes, this is completely unsafe to be driving and making a video – years ago, three years ago, I tried WeGovy and I was like puking," Schumer said in the clip captured while she was behind the wheel.

"I couldn't handle it. I don't know if they've changed the formula or whatever… but anyway, I went on this telehealth meeting with MidiHealth, and it was cheap. I wanted to try it myself, cause I wanted to recommend it to my friends who are like nurses and teachers."

In addition to the injectable medication, which is primarily used to treat type 2 diabetes, the "Snatched" star has a new routine which includes hormones.

"They put me on estrogen and progesterone because I realized I was in perimenopause and my symptoms of being in perimenopause have disappeared," Schumer said. 

"My hair is fuller, my skin is better, I have more energy, I want to get down more if you know what I mean – I'm talking about sex."

She added, "So that's been great, Mounajro's been great… I'm having a really good experience with it and I wanted to keep it real with you about that."

Schumer told Howard Stern earlier this year that she was forced to quit Ozempic due to terrible side effects.

"I have this gene – GDF15 – which makes you extremely prone to nausea which is why I was so sick during my pregnancy. So, I tried Ozempic almost three years ago and I was like bedridden, I was vomiting and then you have no energy but other people take it and they're all good," she said on "The Howard Stern Show."

Astronomers recently discovered a rare interstellar object passing through our solar system, and a Harvard physicist is sounding the alarm that its strange characteristics might indicate it’s more than just a typical comet.

"Maybe the trajectory was designed," Dr. Avi Loeb, science professor at Harvard University, told Fox News Digital. "If it had an objective to sort of to be on a reconnaissance mission, to either send mini probes to those planets or monitor them… It seems quite anomalous."

The object — dubbed 3I/ATLAS — was first detected in early July by an Asteroid Terrestrial-impact Last Alert System, or ATLAS, telescope located in Chile. The discovery marked only the third time an interstellar object has been observed entering our solar system, according to NASA.

Although NASA has classified the object as a comet, Loeb noted that an image of the cosmic visitor indicated an unexpected glow appearing in front of the object, rather than trailing behind it — something he described as "quite surprising."

"Usually with comets you have a tail, a cometary tail, where dust and gas are shining, reflecting sunlight, and that's the signature of a comet," Loeb told Fox News Digital. "Here, you see a glow in front of it, not behind it."

Measuring about 20 kilometers across, making it larger than Manhattan, 3I/ATLAS is also unusually bright for its distance. However, according to Loeb, its most unusual characteristic is its trajectory.

"If you imagine objects entering the solar system from random directions, just one in 500 of them would be aligned so well with the orbits of the planets," he said.

The interstellar object, which comes from the center of the Milky Way galaxy, is also expected to pass near to Mars, Venus and Jupiter — something that is also highly improbable to happen at random, according to Loeb.

"It also comes close to each of them, with a probability of one in 20,000," he said.

The 3I/ATLAS object will reach its closest point to our sun — about 130 million miles away — on October 30, according to NASA.

"If it turns out to be technological, it would obviously have a big impact on the future of humanity," Loeb said. "We have to decide how to respond to that."

In January, seven years after SpaceX CEO Elon Musk launched a Tesla Roadster into orbit, astronomers from the Minor Planet Center at the Harvard-Smithsonian Center for Astrophysics in Massachusetts confused it with an asteroid.
