TW for general touching, tickling

I had a deep tissue massage today and at one point during the massage the therapist had my arm raised so my armpit and side were exposed. She was working on my bicep/tricep and I completely blacked out and couldn’t even feel the work she was doing… which was deep tissue. I pulled my arm down and was able to ask to move on but I couldn’t stop the anxiety/tears. I was shakily breathing and crying and had to explain to this woman who I’ve only seen twice that I have trauma and apparently what she did is a huge trigger. I didn’t even realize it was that bad of a trigger, but thinking back on it I have always been super jumpy whenever anyone tries to touch my sides & I hate being tickled with a passion. The rest of the massage I couldn’t fully relax/ feel the work she was doing, I was numb. It felt like I was being tickled and I was super jumpy during the whole thing. My massage therapist is a very nice lady and is very respectful of my boundaries. She said it isn’t uncommon to have an emotional release during deep tissue work. I just needed to vent because it was a lot to deal with and I’m very triggered
