It turns out that you may just have a case of keratosis pilaris.
In a short TikTok video, Dr Shah, who goes by @dermdoctor on the social video platform, showed off some pictures of the red bumps in their various guises, and explained what the condition is called.
He then goes on to explain that keratosis pilaris is sometimes known as chicken skin or strawberry skin.
At the end, because he is a dermatologist after all, he suggests a few things that you can use to treat the skin condition, should you so desire.
According to the doctor, the best things you can use are Amlactin, CeraVe SA, Eucerin Urea Repair, CereVe Psoriasis cream, whatever they all are.
Obviously, if you're worried about anything to do with it, it's better to consult your GP about these sorts of things rather than watching videos on TikTok.
To be fair, according to the American Academy of Dermatology, it's completely harmless anyway and doesn't need any treatment.
If you're itching or having dryness of the skin, maybe you can get hold of a cream to get that to go away, but it's not going to kill you.
There's also a good chance that the keratosis pilaris will go away of it's own accord over time, so over the years you might notice it disappear.
In case you're wondering what the craic is, and what is actually causing it, the NHS website describes it like this: "Keratosis pilaris is a very common harmless condition where small bumps appear on your skin. It can last for a long time, but there are things that may improve your skin.
"Keratosis pilaris happens when your hair follicles become blocked with a build-up of keratin, a substance found in skin, hair and nails.
"Nobody knows exactly why keratin builds up, but the condition is thought to run in families. So if your parents have it, you may get it, too.
"Keratosis pilaris is not infectious, so you cannot spread or catch it."
There you have it, if you've just been sitting around wondering what was going on with your arms, wonder no more, because the good folks of TikTok have you covered.
