stomach muscle

In March at Indian Wells, Draper retired from his fourth-round match against Carlos Alcaraz because of a stomach muscle injury.

He played only 12 games for Freiburg in the Bundesliga and Europa League this season after a stomach muscle injury kept him on the sidelines from March through September.

“Pain that does occur with a hernia is related to twisting or tightening around the stomach muscle, or retained stomach acid, which leads to heartburn. It’s often difficult to tell the difference between cardiac chest pain and GI-related pain.”

Nadal has been bothered by a stomach muscle for about a week, and the pain became nearly unbearable in the first set of his 4-hour, 21-minute victory via fifth-set tiebreaker against Taylor Fritz in the quarterfinals on Wednesday.

Kyrgios won the first set 6-2 against Auger-Aliassime but said he started feeling pain in a stomach muscle while trailing 4-1 in the second.
