my dad was diagnosed feb 2013. He recently re-started chemo ( single agent - Alimta ) as he started having mild left pleural effusion again. He just had his 4th infusion.
The pain started a couple of days after his 2nd infusion. All of sudden, he had severe pain around the bottom of left rib cage on the side ( where left elbow would meet body when standing up with hands naturally pointing down). He described the pain felt like side stitch. It was worse when he lies on the left side, as well as when he lay down on the back. It felt much less when he lies on the right side. He also felt it when he coughs and does deep breathe. It was bad when it started, but then gradually got better. By the time he need to have chemo again, it almost went away. But then several days after the 3rd infusion, it started again, same place, and then gradually went away before his 4th infusion.
Now he had his 4th infusion. On day 4, he started feeling it again. Although not as bad as previous times, he can still feel the discomfort. We asked his oncologist, who think it was pulled muscle. We also did Colour Doppler Ultrasound (while suspecting enlarged spleen), but result came back normal.
not knowing what is causing the pain, I am wondering if anyone here has any ideas on what might be going on, or what test might help figure out what's going on. Thanks for your feedback in advance.
