Andy Murray is unsure of the severity of his abdominal injury, but is hopeful it will not affect his preparations for Wimbledon.
The three-time grand slam winner struggled with the issue during Sunday's 6-4 5-7 6-3 defeat to Matteo Berrettini in the Stuttgart Open final.
Murray, who was competing in his first tour-level final on grass since 2016, twice received medical treatment but was able to finish the match.
He played five matches in Germany last week and four matches in Surbiton the week before en route to reaching the semi-finals.
Murray is due to play at Queen's this week before Wimbledon in a fortnight.
While frustrated with the manner in which his bid for a first grass-court singles title in six years ended, Murray says it is understandable that he is struggling physically.
"I felt like I was playing well enough to win and I got myself in a really good position going into the third set so a frustrating end to what was a good week," he said.
"I got some pain in my abdomen when I was serving. It's not something I've had before. I'll need to get it checked when I get home.
"This is the most matches I've played in two weeks since probably 2016. That's a really long time.
"It's probably normal that I would feel some stuff in my body but I don't really know the severity of it. Hopefully it's all right."
