Brandi Glanville has revealed her facial parasite has "spread" down her arm.

The 53-year-old star has been open with fans about her ongoing health issues, and she has shared another emotional update on social media.

In an Instagram video shared on Tuesday (08.09.26), she said: "It used to only be here, but over the years that not being diagnosed properly, it has spread. Now it goes down my right arm."

The Real Housewives of Beverly Hills star fought back tears in the video, revealing the large fungal ball in her face.

She added: "It's hard as a rock, and it curves like this. I'm so sick [of it] I just want to cut it out of my face."

She also gave updates on a rash on the right side of her face.

In the caption, Brandi explained: "I'm finally ready to tell you what I've actually been fighting and to start sharing some of my worst moments leading up to finally getting diagnosed.

"I've been diagnosed with highly resistant ESBL Klebsiella and Enterobacter with biofilm, Coccidioidomycosis (Valley Fever), Demodex dermatitis and Mononucleosis."

According to the US' Centers for Disease Control (CDC), ESBL Klebsiella is a kind of antibiotic-resistant bacteria.

The Mayo Clinic says Valley fever is a fungal infection, while the Cleveland Clinic describes Demodex as "a type of mite that lives in human hair follicles, usually on your face".

Brandi noted that her "fungal ball" in her face needs to be removed, along with "metals from old dental work out of my mouth".

She added: "My breast implants need to come out, and I'm looking at 4-6 months of daily IV treatment."

The treatments have "not been easy", and they've cost Brandi between $3,300 and $6,000 a month after health insurance.

Opening up about the emotional and financial toll, she said: "I'm not able to work right now other than my podcast and I honestly don't know how I'm going to do this mentally or financially.

"I'm sharing some really bad moments and I know I don't look good in these videos. Honestly, I don't care. I feel terrible and this is what being sick looks like for me right now."

Brandi continued by asking her followers to "be nice in the comments", and added that she simply wants her "health back".

She wrote: "I just want this s*** OUT of my body. I want my health back. I want my life back. I want to feel like me again.

"I'll be sharing more of what I've been going through, the treatments, the surgeries and hopefully eventually the other side of this."
