22 male, about 1.87 meters, 85-95 kg, quit smoking cigarettes after 7 years, 2 months ago. Quit everything else like alcohol, caffeine and such, over one year ago, although I do still drink one beer every 2 weeks or so, and I do still use nicotine pouches daily. I had tuberculosis at 7 and asthma, although I can't tell if I had any symptoms in years. I also have health anxiety and had it for 3 or so years now, which could for sure be the culprit.

My blood pressure is perfect for my age, and did an ECG, that was normal too.

But sometimes at night I start feeling weak all of the sudden, for no apparent reason, like, feeling as if I am very light, as if I am not even touching my chair or floor with my feet/butt, I often times feel as if I can't think clearly, I never had headaches, but for the past month or so, I had some rather mild and short lived headaches, they are scary, as I am afraid of something being wrong with my heart. The veins on my hands look more constricted, when normally they appear huge too, and my hands get paler.

At the moment I do not get nearly enough exercise, because I am sitting at my desk all day, and when I get out, I feel bad because my lower back hurts.

Either way, I have a picture of how one of my veins looked today on the right side of the neck, it did happen before, and I am not sure if its always like that, I have not payed too much attention to it. Also a pic of my hands veins, that are not visible as they normally should be, and pale.

Does it look normal? I was not anxious when I took the pictures, only after.

Is this vein normally this big?
