First thing...just assure that you have costochondritis. You may be right if you have pain only at single point. If it generalised then you may not be right.
You also have sneezing and features of gastritis/ GERD.
Next Steps
Go for allergy testing if sneezing is recurrent. Start with some anti acidity treatment. If you have breathlessness along with chest pain then consult with your doctor and ask for spirometry
