Active Chronic gastritis. Health issues.

I have been experiencing multiple symptoms for the past 6–7 years, including mouth ulcers, a white coating on my tongue, intestinal inflammation, bloating, chronic gastritis, enlarged and inflamed tonsils, persistent loose stools, and small pimple-like rashes. Despite consulting several doctors and even visiting AIIMS, no definitive diagnosis has been made, even after undergoing multiple tests. I also experience recurrent fevers every 1.5 to 2 months, which leave me feeling dizzy and unwell. All tests related to my chronic gastritis have come back negative. I have also tried Ayurvedic treatments in the past, but they did not improve my condition. These symptoms keep recurring and are significantly affecting my health. I am deeply concerned and feel that my condition requires urgent and thorough evaluation. I would like to consult an experienced doctor who can help identify the underlying cause and provide effective treatment for my long-standing health issues.
