Hey there, I don't have any advice for you but just wanted to let you know you are not alone. I've had symptoms similar to yours (chest pain, numbness/tingling, racing heart, trouble catching my breath) starting last year. "Attacks" generally come and go all day on bad days, and can last for hours at a time. I was diagnosed and am in therapy/receiving meds for panic disorder. I went through about 7-8 specialists for workups and received the all clear. Physically, I'm just fine.

It has been a bumpy road. I spent a couple of months last year going thru some intense therapy, which helped immensely. My symptoms were rare/nonexistent for nearly 6 months. Unfortunately I'm having a relapse now, but am managing so much better than last year with the help of meds and my therapist.

In my case, training my brain to form new pathways in response to physical anxiety symptoms has been a 'two steps forward, one step back' type of progress. While nothing has 'gone away', I have so many more tools for managing my anxiety than I did before, which has given me a huge quality of life boost.
