Does quitting nicotine cause chest pain on the left side?

Hello doctor,

I am a 21-year-old male who has quit using nicotine pouches for about two weeks. Since then I have had slight chest pain (2 out of 10 on a scale) that has developed on the left side of the chest, near the attachment of the pectoral muscle. Since I wanted to reduce the pain I have found that Aspirin could be a wise choice that is not even prescription based. I had taken 100 mg and I began to feel very uncomfortable symptoms. I became extremely focused to the point that it made me anxious, I had cold hands and feet and at the beginning, I was feeling like I was about to die. The heart problem has stopped but the symptoms from the Aspirin are much more of a concern for me. It has been about four hours now, my hands are warmer, and also my feet. I do not feel like death, but I do not feel comfortable going to sleep for some reason, nor do I have the tendency to go. I am writing this because I have a general fear of doctors because my mother is one and I do not want her to find out, that is why I am asking via the internet. Is it safe to assume that nothing will happen if I go to sleep? Thank you for your answer. My usual blood pressure notes were about 90/65 mmHg with a pulse of 80 bpm as of this morning.

Hello doctor,

It has been about eight hours now, I just recently got to the blood pressure device and I have measured a 125/84 mmHg lying in bed with a 98 bpm pulse rate. Sometimes I get a notification on the blood pressure reader that I have an irregular heartbeat. I do not know if I am capable of falling asleep.
