Hello, I have been having digestion issues such as being gassy with difficulty relief from it for a long time. Also, last few months I have had heart burn, and tightness of breath. I have had my heart check and my heart is fine with no relation to the tightness of breath. It has been about a month that I have developed smelling a burn like smell…. For a while I did not think it may be inside my body. After a while I have noticed wherever I go the smell follows me. It is not a body odor :). The smell is in my nose. But, I notice anywhere I went the smell was there too. I have explained to a couple of Doctors, and their reaction was not of a certain diagnosis because they have not tested me for it. But, they thought it may be rising from my stomach(inside). So, I thought to post it here to see if anyone has heard of such an issue, and can suggest what kinds f tests I should have done for diagnosis! Thank you in advance.
