Anxiety & sensations

Hey

I have ADD and I easily get very anxious. When I feel this anxiety creeping up which it does every single day & for most part of it I get very strange sensations in my body.. I seem to focus my attention when Im anxious on body parts much more than I would if I was feeling "normal"

Before I always focused on my heart, and I would get this weird pain, but not in the heart but in some nerves in my chest.. I have the same thing with the groin.. When Im anxious or even scared I seem to get a weird feeling in the groin and a extreme tension in my adductor muscles in my buttox and legs.
This is really freaking me out & I am wondering what its all about?? I dont know if you have any clue or if its just my anxietys way to take a physical form or "made up" form?? I also have to say that I get this weird tension in my whole body I think, I also have a really hard time breathing which often leads to panic attacks but the thing that really bothers me is the groin thing..
I read alot & I stumbled on something called groinal response when feeling anxious

Does any of this make sense?
Please help!
