Uppercut by heavier upper belt during Uchi-komi
I'm a 60 kg white belt, was paired with the only other woman, 73+kg blue belt. We were doing the lapel shoulder throw, she was being very forceful, sloppy and fast with her technique, but I didn't voice complaints because of her upper belt (I assumed she knew what she was doing through the red flags). Somehow she managed to squarely uppercut me in the chin, given she was being EXTREMELY forceful and explosive for drilling, it wasn't a light hit. I stopped drilling and drank water, I was livid, didn't say much given I wanted to keep it under wraps and keep decorum.
She apologized once, in between some variation of I was "stiff" so she had to use maximum force so actually it was my fault she squarely uppercut me boxer style while grabbing my colar (reminder we were bloody drilling technique I was static and unmoving, her only job was to grab my colar and lift me*)*.
(I've grappled for 3+ years now, I'm a white belt here but give me a fucking break, I've been training judo for 3 months so I don't tense anymore, aside from propper breakfalling I was something akin to a upright ragdoll)
I'm bloody pissed at her, luck is she and I are often the only women at the gym. So I am stuck with her as a training partner. Of course had a nasty headache and I'm pretty sure one of my tooth fillings is shot now. I hope I'm not concussed, given I've had concussions before and I am more sensitive to them. What should I do about this?
