Long-distance partner has an unexplained rash and I am worried

I've also posted this in the Sex section...

I'm in a long distance relationship and I've just got off the phone with him, did a video call and he was sitting in a short sleeved T shirt due to the heat. He usually wears long sleeved shirts. I spotted a really odd rash on his left arm, kind of purply blotchy that looked as if someone had put a cigarette out all over it, from around his wrist, on the forearm, up to the elbow and a little above. It also had a yellowish tone to it underneath, if that makes sense.

Due to family issues, we haven't been able to see each other in person since early January. We usually see each other several times a year and there are plans for him to come to me. I asked him about the rash and he said he had had it since January, but it must have been after I came back home, so like the third week. He said he hadn't been to the doctor about it.

I thought that was odd, he has full health insurance, lives in Germany so never a problem to get the right treatment. He said he didn't want me to worry, which is why he never mentioned it. When I asked how and where it had started, he said under his left armpit, like a nodule, and that the nodule had fluid in it, it burst when he scratched it. Then the rash on his arm appeared and the spots also had fluid in them. So what is there now is apparently scars.

He promised to see a doctor, but I don't understand why on earth he hasn't yet if it has been there since late January and especially after a "good friend" said it could be skin cancer!!! I have had an odd gut feeling that he hasn't been faithful, I don't know why, just an inkling. When I've looked for STD skin rashes online, his rash kind of looks like syphillis... Now I'm freaking out. Going to see my GP asap after the Bank Holiday. I've had no symptoms at all, but then we always use condoms.

Has anyone had any experience with this kind of thing? I have a photo but not sure if I'm allowed to post?

If he had a cyst under his armpit that burst, and then this rash appeared, it sounds more like cellulitis than an STD. Either that or he’s had shingles.

However, if you’re so panicked that you intend to see a Dr for screening asap, then you obviously don’t trust this guy, so I would ask yourself, is it worth even being in this relationship?

That’s a really big leap op! It could likely have been something like bullous pemphigoid, or as the previous poster said cellulitis or shingles. What made you jump straight to a sexually transmitted disease?

Thanks for the replies. I think the big leap was for a few reasons. We usually tell each other everything. We've been together for a really long time and back in February I caught head lice and scabies as I work at a school. It prevented me from going to see him for a few weeks as I needed to make sure I couldn't infect him. Or anyone else!

So a bit off from that perspective. He asked me to come for a long weekend in March, but I couldn't, but he never mentioned the rash at all. He had said he felt like he had flu. Odd behaviour not to share the details with me. On the video call his face looked guilty and his body language was off. Again, when you've know someone for a long time, you notice these things.

I started feeling suspicious and looked up STD rashes and a few images popped up that look similar. It also looks like it could be ring worm. When I suggested ring worm, he became a bit defensive. So again, it was the odd behaviour and body language.

There have been incidents in the past of broken trust, but we've repaired and continued. But I find it bad that he would invite me for a visit with something potentially infectious, whatever it is, and just not bother to even mention it.

So this is his left arm.

Also thinking fungal infection (ring worm is one yes?), but why would it scar like this? He definitely needs a GP and the more I think about it, the more annoyed I am that he hasn't been. There are vague plans on the table for him to visit me in two weeks time as well...

I cant understand why he hasn't been to a GP with this OP. It looks awful.
I don't know what it is but I did do a Google image search of your photo and it says it's unlikely to be Syphilis.

It looks like the scars from dermatitis but until he goes to the doctor/dermatologist neither of you are going to know for sure.

If you're suspicious of him, bin him, don't hang about. If you want to stay force him into getting it seen to.

ForeverDelayedEpiphany · 25/05/2026 22:36

It looks very sore on his arm, OP.

From my quick Google search, if I was just going by the pics, it says it could be anything from Sjogren's syndrome, to a rash caused by lupus - so clearly, it isn't a reliable diagnostic method..! 😐😳

Seriously though, I'd definitely be telling him to go to the doctor's and get it checked out properly.

Ringworm can also be sexually transmitted- I've never heard of anyone catching scabies because they work in a school- also usually sexually transmitted.
