Hello,
welcome to Healthcare Magic.
In history you mentioned that, you had already evaluated by cardiologist and tests are fine, then we should suspect anxiety or stress for cause of current symptoms.
Your symptoms are appear to related from 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, choking sensation,
dizziness, tremors (shakiness) etc. You already have some of these symptoms.
For long term control of anxiety following measures are helpful: relaxation exercise, medicines like SSRIs and non drug treatment like CBT. It is better to get evaluated by
psychiatrist and start treatment accordingly.
Same time do some relaxation exercise like daily brisk walk, yoga and
breathing exercise, which will help you in fast recovery.
Wish you good health and all the best.
Regards,
Dr Ashish Kumar Mittal
