Hi. This can be a classical xiphoid syndrome . A nice course of steroids ( if you do not have diabetes and hypertension), anti-inflammatory medicines like Ibuprofen in proper doses , local heat fomentation, Avoiding any movement that causes stress on this area , like getting out of the bed in straight-up position ( roll over), bending , stretching, take mild laxatives for good motion, helps a lot. IN such patients if the above things do not help , I do take the patient on my own to the Sonologist and ask him to do USG with the highest frequency probe to see if there is a gap in the central line with protrusion of small fat lobules in linea alba. Please discuss this with your Sonologist. I hope this will really help you a lot. I few of my patients I do advise to remove the xiphisterum and explore the linea to see small hernia entrapping the fat. If yes treat accordingly. This is done only if medical treatment fails.
