I think I have anxiety I’m 17 and I always have left side chest pain, my arm feels weak/a lil numb and sometimes quick sharp pain in arm, dizzy, shoulder pain,and back pain. Could this be physical anxiety symtpoms?
This has been going on for almost 2 months.
Yes, this could definitely be anxiety. I will say that at 17 your chance of anything heart related is slim but you should go and talk to your doctor about your concerns. You said it had been going on for almost 2 months but didn't say if you have been checked out for it and didn't say if you have been diagnosed with anxiety or not. SO if you have NOT been checked out for it, please do so. If you have and have been told your tests are good and you do have an anxiety diagnosis, then yes it can definitely be from your anxiety and you should talk to whoever you see for that. Best of Luck!!!
Im sorry I completely forgot to include that, ive had blood tests and chest xrays and everytjing has came back fine.
"Could this be physical anxiety symtpoms?"
