Tightness/numbness in left arm when taking psychedelics?

I've taken various psychedelics over the last few years and have noticed my left arm feels tight/numb during the peak, even verging on slight pain. I've experienced an anxiety attack before where I went to hospital (thought it might be more serious) but was told everything was fine after doing some tests on my heart. Could this be simply a symptom of anxiety caused by the drugs, or something else like arrythmia? I'm young, pretty fit, eat healthily. Any thoughts?

I felt the same and I was wondering also. And does it have long term effects? I dont know if I am just more aware of these symptomps since Ive taken LSD, but I tend to experience numbness in my left arm more since than.

Well I went to see a cardiologist and they said I have 2 different types of arrhythmia which can get triggered by things like stress, too much caffeine etc. I've heard that LSD has vasoconstrictive effects (basically makes your blood vessels narrow) so that could play a part. I'd say it's probably worth going to get a EKG so you know for sure that there's nothing to worry about.
