NOW WEIGH! I've lost 5 stone on Mounjaro but have a 'painful', 'burning' side effect no one talks about – it's driving me crazy
A WOMAN who dropped five stone using Mounjaro has warned other users of a 'painful' side effect that's making her life hell.
Ann, who shares her weight loss journey on TikTok, opened up about her lesser-known struggle after taking the popular jab for 40 weeks.

She says the treatment, which has helped thousands shed serious weight, has left her with extreme skin sensitivity that feels like 'burning' and 'sandpaper'.
And despite trawling the internet for answers, she says there's little info on it and wants others to speak up if they're suffering too.
In the video, she explained: 'I've been on Mounjaro for 40 weeks and lost about five stone.
"But one thing I'm really struggling with is this skin sensitivity. It's a side effect that just isn't spoken about.'
Anne described the sensation as 'painful and burning', adding that the affected area becomes so sensitive, it hurts just to touch.
'It feels like someone's taken sandpaper to my skin,' she said.
She claims the pain, which is on the outside and back of her thigh, hip and knee, is extremely painful, driving her crazy.
She added that it's so bad, she can't sleep properly because the discomfort keeps her up at night.
While she initially thought it could be linked to her injection site, she recently switched from stomach to thigh and the pain appeared on the opposite side, ruling that out.
I went on fat jabs but the hair loss was unbelievable so I quit - I'd rather be chubby with hair than skinny and bald
The comment section lit up with others saying they'd experienced similar but, like Anne, couldn't find much official guidance.
One fellow user said: 'Yes, I've had it too. It's not spoken about enough!'
And Ann's not the only one raising the alarm.
Other TikTokers have reported soreness, itching, and acne since starting Mounjaro, with many saying they feel 'hypersensitive' in the sun.
In fact, one Mounjaro user recently warned followers to up their SPF game this summer as the drug can make your skin more prone to burning.
That's why experts are urging anyone on GLP-1 meds like Mounjaro or Ozempic to step up their sun protection game.
Skincare brand HydroPeptide has dropped a high-end range of SPFs packed with peptides and soothing ingredients to shield sensitive skin.
Their Sun Slick SPF 50, which retails for £32, offers non-nano zinc oxide for gentle protection that doesn't absorb into the bloodstream which is ideal for irritated or inflamed skin.
Or there's Solar Defense Body SPF 30, which is perfect for full-body coverage and packed with antioxidants to calm sun-exposed skin.
If you're looking for a more budget-friendly option Superdrug now stocks Bioré Aqua Rich UV Invisible Face Mist SPF 50 which is a handbag-friendly spray you can mist over makeup.
It's already earning rave reviews for being an on-the-go SPF essential.
Meanwhile, skincare brand Image has launched the first ever GLP-1-friendly moisturiser designed to tackle so-called 'Ozempic face' to help fix the gaunt, sagging skin look.
So if you're shedding the pounds but feeling the burn in more ways than one, you're not alone.
Ann says she's speaking out in the hopes that others will share their experiences too and get the support they need.
Because when it comes to Mounjaro, weight loss might be the headline but for some, the side effects are the real story.
Meanwhile, experts are getting candid on a fat jab complication that might shock many.
From eggy burps to stomach-churning nausea, there appears to be an endless list of side effects linked to Ozempic-like jabs.
