She then shared a snap of the red lump before a doctor told her to draw a circle around the swelling to see if it got bigger. Unfortunately, the swelling appeared bigger overnight. "Of course, it got bigger… and bigger. Full on swollen leg," she added.
Eventually, Steph revealed he was diagnosed with Cellulitis and is on antibiotics. However, the medication will now play havoc with her IBS.

"Gutted I have to take antibiotics because it wipes out the good bacteria in my gut, which means my IBS will probably be bad again." In a tongue-in-cheek remark, she then said: "Still, better than sying of sepsis."
Cellulitis is a skin infection that's treated with antibiotics. According to the NHS website, it can be serious if it's not treated quickly.
"It is usually caused by a bacterial infection," the website reads. "The bacteria can infect the deeper layers of your skin if it's broken, for example, because of an insect bite or cut, or if it's cracked and dry."
