The US Open champion retired just seven games into her first-round clash with Switzerland's Viktorija Golubic after suffering a problem with her left side.
Raducanu has been plagued by injury problems in 2022 and the latest setback has left her participation at SW19 in doubt.
The British number one said: "The first game an absolute freak. I think I pulled something, I am not really sure what exactly happened.
"I have just come off court, an absolute freak injury.
"I don't know what I could have done more about it. That is it.
"I need to get a scan first. I am not going to 'Google doctor' myself. I will get it checked out. Then we will see from there.
"I have no idea (about Wimbledon). It could have just seized up and gone into spasm and then it is really bad for a few days.
"I have no idea. I cannot diagnose myself. I will get it checked out."
Raducanu insists that the latest problem is not related to her recent back injury as she lamented her persistent fitness woes.
She said: "I am trying to keep that positive mindset that I have been having.
"I have prepared really well for this tournament. I was feeling good, comfortable and I think even when I was out there, there were signs I was happy with playing more aggressively and stuff. It is just a shame.
"I am obviously disappointed and it is really bad luck. Sometimes I feel like I have been putting really bad work in and it is almost like you just want to catch a break but I haven't really.
"That's out of my control, but right now all I can focus on is what I am doing and I think I am doing a lot of good work. I just need to trust that it will come and right now it is happening for a reason and I am exactly where I need to be."
