Teddi Mellencamp had scary symptoms before learning she had several brain tumors.

And the star shared them with her fans so they know how to react in case they suffer from a similar problem.

The former Real Housewives of Beverly Hills star, 43, talked about her cancer battle when chatting with Deborah Roberts on ABC’s Nightline on Thursday.

Mellencamp had debilitating headaches for months, until one day her vision was severely impaired: ‘I couldn’t see. I mean, I could barely get down the stairs.’

The blonde beauty quickly called her estranged husband, Edwin Arroyave, 47, who rushed her to the hospital. 

‘That’s when they said I had four plumb-size tumors in my brain and then within the next day I was in surgery,’ she told Roberts. 

Teddi Mellencamp, 43, has opened up about her cancer journey following the removal of four brain tumors during emergency surgery in February 

‘My first real memory was looking up and my entire family was there. My dad, my sister, my brothers, all of my best friends, and I’m being like, “Hold on, why are y’all here? And chatting? This must be bad,”‘ she explained with a chuckle.

Since then she has undergone radiation therapy to shrink remaining tumors, including some in her lungs, ringing the bell to signal the end of that treatment in a video on social media. 

The health coach is still undergoing immunotherapy.

‘One of my favorite things to ask is “How long I got?” or “What are my chances?” and they oftentimes say “fifty-fifty.”‘

‘Fifty-fifty? I wouldn’t buy a car that’s only gonna drive 50-percent chance of the time. I don’t want this,’ was her reply. 

Mellencamp said that her doctors explained the reason for those odds were that immunotherapy had only been around for about a decade ‘and that’s how long the study has worked.’

Mellencamp uses humor to distract herself from the seriousness of the situation.  

‘If I didn’t find humor, I would cry. Even with my kids, like, the other day, we kept forgetting something and we’d all just go “the tumors.”‘

‘I think I had about 16 different surgeries with melanoma… my whole back is pretty much, it looks like a big Z,’ she  told Deborah Roberts on ABC’s Nightline on Thursday. ‘This last check for skin therapy, they were like, “this is the first time you’ve been clear”‘

That good news was quickly overshadowed by debilitating headaches she had been suffering from for months, until one day, ‘I couldn’t see. I mean, I could barely get down the stairs,’ she told Roberts

After being rushed to the hospital, doctors discovered four brain plumb-sized brain tumors and others in her lungs 

The former ‘housewife’ admits her condition means she can’t do everything she used to do. ‘Night times are really hard for me, so people come and (Edwin) organizes all that. He’s doing the best he can.’

The couple have put their divorce on hold for now, and Arroyave is standing by his wife of some 14 years. 

On a recent episode of The Eds podcast, Arroyave revealed he was all in. 

‘People think that’s hard, but for me, that’s just what I do,’ the  entrepreneur explained. 

‘Like it’s no matter what, I will always love Teddi and she’s been a big part of my life. And I like taking care of people, it’s just what I do. So it wasn’t even like, a question.’

As a result of her condition, Mellencamp has been dealing with changes in her physical abilities and her appearance. 

Mellencamp recently completed radiation therapy, but is still receiving immunotherapy. She said doctors have given her a 50/50 chance of recovery  

Mellencamp has been supported throughout the process by her estranged husband, Edwin Arroyave, 47. The pair have put their divorce on hold 

The couple are parents to daughter Slate, 12, son Cruz 10, and daughter Dove, five

‘I had a good cry yesterday when this part went bald,’ she said putting her hand on the affected area, ‘but we sprayed it,’ adding ‘it’s really going to grow out post-cancer, I can feel it.’

She has been trying to keep up activities to the best of her abilities. ‘I can’t run, but I can go on a walk,’ she explained.

Th wellness coach has been following her own counsel and setting goals. ‘We have our horse nationals and the second my daughter and I got in, I made a goal. I’m gonna start getting back to training so that I can do it too.’

The cancer has taken its toll on Mellencamp physically. ‘I can’t run, but I can go on a walk,’ she explained

She has also returned to competitive horseback riding and has entered a national competition with Slate. ‘, ‘I wanted to have the opportunity to do it with her, just in case this is my last chance. Not a lot of mother-daughters get to do those things and we love it’

Becoming tearful she admitted, ‘I wanted to have the opportunity to do it with her, just in case this is my last chance. Not a lot of mother-daughters get to do those things and we love it.’

Mellencamp and Arroyave are parents to daughter Slate, 12, son Cruz 10, and daughter Dove, five, along with Arroyave’s daughter Isabella.   

She has drawn strength from her famous father, Rock and Roll Hall of Fame member John Mellencamp, 73. 

‘It’s hilarious. I called him, like, “Dad, I’m bald today,” and he’s like “well it could be worse”, ‘I’m like, “how!” ‘You could be dead.’

On the Wednesday episode of her Two Ts in a Pod podcast with Tamra Judge, Mellencamp explained the rocker had called to make sure she would be laid to rest in the family mausoleum.

The patient said she has drawn strength and humor from her father, rocker John Mellencamp, 73, who ‘always taught me to be a fighter’

‘I had a good cry yesterday when this part went bald,’ she said putting her hand on the affected area, ‘but we sprayed it,’ adding ‘it’s really going to grow out post-cancer, I can feel it’

When she told Roberts about her dad’s reaction, revealed the dark humor they share.’It’s hilarious. I called him, like, “Dad, I’m bald today,” and he’s like “well it could be worse”, ‘I’m like, “How!” ‘You could be dead’

For now, Mellencamp is taking each day as it comes. I’m here and that makes me feel good. These are special times that we get to do any of this’

‘He goes, ‘Well you’re doing your will right now, so you may as well put it in there.”‘

In spite of the dark humor, Mellencamp said her father ‘always taught me to be a fighter.’

For now, the determined patient is taking each day as it comes.  

‘I think the biggest thing is don’t take anything for granted. Normally, I’m used to running seven miles, today, I’m barely walking one, but you know what? I’m here and that makes me feel good. These are special times that we get to do any of this.’
