Hello,
Brief answer: You may have
panic attack problem, if that out of control, stop driving and seek
medical advice.
Explanation: My opinion is that
chest tightness, sweating,
dizziness, sense of dying, etc., when happen in certain conditions, like driving in your case that means it is a panic attack, sure that is an exclusion diagnosis after doing some examination and labs. It seems that this condition is affecting even you sight accuracy and that is too risky as you're driving. So you need to be careful, if things are out of control, you should seek medical advice.
I suggest my patients the following: Do some physical examination, ECG, and if everything is normal, give some drugs like
Prozac or other selective serotonin reuptake inhibitors. Stop driving if that is dangerous. The information provided by you is not sufficient to provide a good opinion. If someone comes to me with this condition I would ask them about similar attacks in other conditions.
Conclusion: I suggest you seek medical advice and do not take risk driving if that is dangerous.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Mahmmad Gamal
