No, 'medical' problems at the very least would imply something biological. It sounds extremely strange to say that a inorganic device could have a medical problem.
I think your 3DS has problems. I don't have that problem (and probably almost all 3DS owners don't either). Or it could be a problem with your wireless internet.
They can have any of the same medical problems as other dogs, there are no specific problems they have.
It is POSSIBLE but VERY, VERY unlikely, only people with severe eye problems/conditions may experience seizure. But then again if somebody had such a condition, they wouldn't buy a 3DS.
The 3DS XL came after the 3DS.
Yes no metter what 3DS is a 3DS
There is no such thing as a 3DS DSi.
No, it is not out for 3DS.
yes
You buy ds or 3ds games and then put them in your 3ds.
No, It's for both 3DS and 3DS XL. 3DS XL is just a larger version of the 3DS.
Basically the 3DS XL is a larger 3DS so if you want a larger screen size, go for the 3DS XL. The 3DS is cheaper and is smaller if the XL is too bulky for you.
The medical problems that can be fixed by a cervical disk surgery are all back problems such as rupturing a disk in one's back which can cause the need for surgery.
