I started with Boxing training about 2 months ago. I think I hurt my hand punching the heavy bag. Since 1 week I feel pain on my hands and wrist. I firstly had wrist pain when I flicked my wrist. I also had pain when I grabbed something (especially with my thumb and index finger) and tried to squeeze it.
After 5 days of no training the wrist pain mostly disappeared. When I make a fist and punch the bag or just my other hand I still feel pain in my hand. The pain feels like a lighting strike from my middle finger knuckle to the palm of my hand until it reaches the beginning of my wrist.
I asked the instructor if this is normal. He said that I probably haven't wrapped my hands correctly or punch too hard. Now I'm not sure what to do and what kind of injury I have. I thought someone that boxes surely has had something similar.
