Hi, just wondering if I should be concerned about this. I'd like to preface this by saying I have health anxiety but would just like to clarify whether or not this is a concern.

I went to the physio earlier today and spent a longer amount of time than normal in the bed having my chin forced into it/pressed against a towel etc. 8 or so hours later I noticed some marks on my chin that looked like broken capillaries or something- like a love bite but without the surrounding bruising.

However, when I pressed on them they didn't fade at all, so I began to worry that it was a serious illness associated with a rash that doesn't fade.

Because of my anxiety I have been checking my body regularly for the rash to see if it's been spreading. I noticed on my arms some very tiny (almost microscopic, but varying in size slightly) spots. They are bright, fire truck red and, like I said, absolutely tiny. The largest one is perhaps the size of the head of a pin. However, I am unsure as to whether or not they were there before or they've come about since the marks on my chin. Unlike the marks on my chin, almost all of them fade when pressed down or when I drag the skin. They are flat and look as if they're just on the top layer, but I can't exactly tell. Some of the slightly larger ones look like thread or a splinter just under the skin, with a bright red for and a pinkish tail. I squeezed the largest one and it sort of popped though, it seemed slightly raised like a blister. The mark still remains, though.

I feel as if these marks may be spreading, which is why I'm contacting you (when I last counted there were 5 on my left arm, 8 on my right and 2 on my chest). It's currently early in the morning where I am and I'd rather go to sleep than stay up all night fretting or go to the hospital, but I thought I should make sure.

Other than these mysterious marks, I feel absolutely fine if a little tired because I didn't sleep much last night. However, as you can probably tell I am very anxious- can anxiety cause such marks to appear? Sorry for my long-winded question and thank you for your help.
