This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
Xiphoid process inflammation will cause such pain.
Viral infection or excessive physical activities can cause the inflammation of the cartilages attached to xiphoid process.
Any stretching activity will trigger the pain.
Complete rest, and use of anti inflammatory medication like Ibuprofen 600 mg 3 times daily should help.
You can apply warm compress as well.
In severe cases, steroid injection at the joint will help to resolve the symptoms.
I will also suggest chest xrays to rule out any tumor or growth behind the xiphoid process just in case.
It was my pleasure to help you today.
