[profound (OP)]

My son has been hitting a punch bag and now claims to have stomach pain located mostly near the middle of the stomach in a 6 inch diameter spot.

i wonder if it has any connection to hitting the punch bag.

The hospital doctor has proscribed 2 buscopan tablets 4 times a day.

He may have strained his abdominal muscles. This is quite common. Is the discomfort postural? i.e. if he does a "sit-up" movement, does that elicit the same pain? And is there any point-tenderness: can you press on a place and cause the pain? And is the pain fairly close to the surface, or does it feel like it's coming from deep within?

If he's preparing for a boxing match, consider the possibility of a psychogenic cause, ( how good/big is his opponent ? ).

Punching something can strain the abdominal muscles by overexerting the muscles or temporarily increase the pressure inside the abdomen and cause soreness. As expected, any serious abdominal pain after hard exertion should be evaluated by a doctor!

[Grazzironi]

High-intensity exercise like boxing or kickboxing(even hitting the unch bag) can cause overextension. This can cause muscle damage and rupture that requires intervention and rehabilitation. Overtraining and metabolic buildup in the tissues and joints are very common in professional martial artists and even kids who do this kind of sport. If the pain doesn't go away on its own, I think it would be best to consult a doctor.

Did you ask the doctor?  His opinion would be much more reliable than anyone here.

A bit of pedantry:

• Prescribed: advise and authorize the use of (a medicine or treatment) for someone, especially in writing
  
• Proscribed: Forbid, denounce or condemn

Not sure I would call it pedantry

You'd be surprised how many newsreaders, voiceover actors and spellcheckers can't distinguish hyper from hypo, or diffuse from de-fuse. All good life and death stuff.

Nobody should be allowed to write or broadcast without a  recognised qualification in Latin or ancient Greek. And some who have, still shouldn't open their mouths in public.

I think it may be better if they had a qualification in the language in which they are actually broadcasting.
If they are doing more than reading a script, it would be better still if they were qualified in the subject about which they are broadcasting.
For example, endocrinology might usefully be left to endocrinologists.

Meanwhile idiots with degrees in Philosophy, Politics and Pig-husbandry are selected to broadcast on any subject on which they are profoundly ignorant, regardless of the facts, because they also know a bit of classical Greek.
