Hi. Thanks for your query, albeit short and specific. Read and understood that you have pain in the right side of abdomen and the lower chest, you Doctor has opined that it is due to anxiety. Yes, this looks to be a costo-chondritis wherein there is inflammation of the cartilage part of the ribs. The cause are post-viral flu post -infective pathology like Enteric fever. Most of the patients already suffer from IBS and some psychosomatic problems. I would suggest you the following: -Rest to the area by means of strapping with the Adhesive tapes during the deep Expiration phase. This will limit the movement, reduce the pain and give rest for healing to occur. -Anti-inflammatory medicines in full dose as per the weight. -Steroids if required for its strong anti-inflammatory role. -Diuretics to reduced the edema. -Control of stress and anxiety helps a lot. -Local rubrafacient liniments if the area is not covered by strapping. -Confirmation of the diagnosis by local Doctor on palpation and clinical evaluation and to get prescription based medicines after discussing the above points.
