Hi. Thanks for your query. Noted the history of cough and cold, bad chest pains in the ribs that continued particularly where ribs meet at sternum. This is classical of costochondritis and I would advise 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.
