Hello,
welcome to Healthcare Magic.
Your symptoms are related to anxiety. Anxiety disorders can manifest not only with psychological symptoms but with a variety of physical symptoms also like:
Tingling, numbness, hot and cold sensations,
palpitation, chest heaviness, weird sensation (bubbling feeling) and
dyspepsia etc.
In history you mentioned that, you had already evaluated by GI specialist and they are not doing
endoscopy, which mean they do not feel its need in your case. Cancers are rare in young age. Excessive health worry is also a symptom of anxiety.
It is better to get evaluated by
psychiatrist and start treatment accordingly. for anxiety related issues. For long term control of anxiety following measures are helpful: relaxation exercise, medicines like SSRIs and non drug treatment like CBT.
Wish you good health and all the best.
Regards,
Dr Ashish Kumar Mittal
