Travis Barker is said to be "doing better" after he was rushed to hospital in Los Angeles on Tuesday evening.
It has been reported the Blink 182 drummer, 46, is battling pancreatitis, with doctors believing it was triggered by a colonoscopy.
Now sources say Travis is making steps in his recovery, with his wife Kourtney Kardashian staying by his bedside to "lift his spirits".
"He was in extreme pain yesterday, and he and Kourtney were both really worried, it was to the point where he could barely walk," a source close to the reality star told E! News.
The insider added Travis is expected to be "ok and is doing better".
They said: "Kourtney is trying to lift his spirits and hates seeing him in excruciating pain."
Mirror Online has contacted Travis and Kourtney's representatives for comment.
Travis was hospitalised shortly after the concert and just hours after cryptically tweeting: "God save me."
The now-ominous tweet sparked concern amongst fans when Travis was pictured entering an ambulance on Tuesday night, but many have since pointed out the phrase is also the title of a track by one of Travis' pals, Machine Gun Kelly.
Pancreatitis is a condition in which the pancreas becomes inflamed over a short period of time and is a rare potential complication following a colonoscopy.
Symptoms include intense stomach pain, vomiting and fever.
It comes as Travis' step daughter Atiana De La Hoya - daughter of his ex-wife Shanna Moakler and Oscar De La Hoya - has taken to social media to acknowledge the "outpouring of love" for her former stepfather.
Posting to her Instagram Stories, the 23-year-old wrote: "Thank you for the outpouring of love and prayers sent our way at this time. It is heard, felt and appreciated Xx."
Atiana then went on to share multiple videos of Travis and Shannon’s 18-year-old son, Landon Barker, performing on stage with Machine Gun Kelly at Madison Square Garden in New York City Tuesday night.
Meanwhile, Travis' daughter Alabama Barker also took to her Instagram Stories to say: "Please send your prayers."
Later, in a now-deleted image originally shared on her TikTok page, 16-year-old Alabama posted a photo of herself holding her dad's tatted hand while he was sat upright in a hospital bed.
The snap showed Travis wearing a black brace over his wrist and thumb while he holds his phone in the other.
He was also seen wearing a white hospital identity band around his wrist, which Alabama covered with a pink heart emoji to hide Travis' personal details.
Wife Kourtney is yet to comment or break her online silence regarding her beau's health woes, but it's reported she 'won't leave' her husband's side.
Travis' medical emergency comes just over a month on from the drummer tying the knot with the reality TV star with a third ceremony at a lavish event in Italy on May 21.
