OK, odd question!

I got banded 8 weeks ago, all going well, and I've got back into kickboxing for exercise.

But a good friend has just started a grappling class, and is raving about it. I'd love to take part, but I'm worried about the port - namely if there is 'grinding' contact, can that cause problems? There is a lot of force involved when I grapple with 'the big guys' and I worry about the port getting shifted about a bit

So has anyone gone back to wrestling/judo/bjj post op?

humm... not sure if i can help you there, but i would be worried about getting jabbed or kicked or something in the port. that may cause some damage. I would consult your doctor first and see what he says.
