Tingling sensations in my body and hands after session

During today session I felt anxious like I was not really able to talk, a lot of silences, maybe I'll write the specifics later. I felt more present tho, like more in the present moment and my T said that too...like sometimes when I speak and are talkative I space out a bit like I'm not focused on my surroundings (even tho I remember everything).
My T said that there's some sort of "block" in my chest associated with anxiety and it's true really. He was really sweet today and comforted me with some words...he was really there, engaged and made sure that I was ok and in a safe place.
After the session I came back home...and I'm feeling tingling sensations in my entire body, and in my hands...my hands are hot and a bit sweaty but it's not an unpleasant sensation..it's like "energy" is flowing? And I feel gastric movements in my stomach, I don't know how to explain this but it's weird. But I'm not feeling bad really. I feel like my mind is clear, not sad.
I think there's a connection with therapy, I don't know maybe it's about the bond with the therapist?

Now that I remember his words, he said "I feel like you are more present today that you are feeling anxiety" and I said it's true because when I'm talkative here, sometimes I'm not really focused...I'm thinking, is it bad if I'm unfocused? Like maybe it's a bad thing and is bothering him? Gosh I should overthink less xD

It sounds a bit like an anxiety symptom, or maybe the after effects of an anxiety attack. I think it's still early days in your therapy, and you are probably still just getting used to being in your T's presence. It can take weeks, months, or years to feel safe.

I read somewhere that talking quickly but in an unfocused way can almost be akin to dissociating. It's a different sort than spacing out and falling silent, but it can serve a similar purpose during moments of strong anxiety. If your T commented on your focus in any way, I'm guessing he's thinking about your anxiety levels and it has nothing to do with him being bothered by it.

I don't know how an anxiety attact feel like, I never felt anxiety during the last days, only a bit with that girl but not constantly...it's like the anxiety wasn't there. but I think maybe the tinglings were a release from the anxiety? like my body wanted to release?

I️ have tingling in my hands and feet quite often when I️ am meeting with my counselor. Sometimes it’s stronger than other times. A lot of it is connected to what I’m working through and the intensity of it.

This past Wednesday, when I️ got to his office the ends of my fingers were numb. Sometimes it feels like there is “electricity” in my feet. It really varies depending on what I’ve worked through in my journal that week.

My counselor asks me how I’m feeling when I️ get there and depending on the intensity sometimes he helps me do some grounding and it decreases it.

I️ also have a part of me that I️ call the babbler. It’s the part of me that talks, as you describe, and I️ become a passenger just listening, with no way to stop it. I️ do agree that it is a dissociative part.

I️ have experienced other body sensations which I️ believe are body memories.

But I'm not dissociating really, like for example I'm that talkative with my sister or when I'm by myself (yes I talk out loud when I'm on my own sometimes to think better), I'm still in control of my thoughts it's not like I'm watching myself. When I'm in therapy I feel a bit unfocused from my surroundings, so maybe it could be a small dissociation? I usually experience it when I talk in public or when I talk but feel anxious or self conscious, I tend to forget my public and focus on my words.
Maybe I should mention these tinglings to my T next week?

I think that tingling sensations in different body parts can be quite typical symptoms of anxiety - you can see it listed if you search for anxiety symptoms. Also, I agree that anxiety can be associated with feeling more present. Being anxious means a hightened, even exaggerated level of awareness, hypervigilance. I often find that when I am moderately anxious, it enhances my performance and groundedness vs when I don't care, public speaking is a good example. Of course if it is too much, it can have the opposite effect and become inhibiting.
