First and foremost, congratulations on quitting smoking. That's a significant accomplishment, especially after many years of smoking. The symptoms you're describing post-quitting are not uncommon, but they can be concerning and disruptive to your daily life.

Many of the symptoms you're experiencing, like the feeling of crawling under the skin, tingling, sudden pain, and tightness in the chest, can be attributed to nicotine withdrawal and anxiety. Nicotine withdrawal can manifest in various physical and psychological symptoms, and anxiety can exacerbate these sensations.

It sounds like you might be experiencing health anxiety, especially given your focus on your chest area and the fear of what might be happening. Health anxiety can cause individuals to become overly aware of normal bodily sensations, interpreting them as signs of serious illness.

Managing Symptoms and Anxiety:
- Continue with Healthy Practices: Practices like yoga, walking, and maintaining a healthy diet are excellent. They not only improve physical health but also have a positive impact on mental health.
- Mindfulness and Relaxation Techniques: Techniques such as deep breathing, meditation, or progressive muscle relaxation can be beneficial in managing anxiety.
- Cognitive Behavioral Therapy (CBT): CBT is particularly effective for health anxiety. It helps in understanding and changing the thought patterns that contribute to your symptoms.
- Support Groups: Consider joining support groups for individuals who have quit smoking or are dealing with anxiety. Sharing experiences with others who understand can be very helpful.
- Consult a Mental Health Professional: If you haven’t already, consider seeing a psychologist or psychiatrist. They can provide tailored strategies to manage your anxiety and any other underlying mental health issues.
Acknowledge Your Progress: Remember to acknowledge the positive steps you've taken. Quitting smoking is a major life change, and it's normal to experience a range of emotions and physical symptoms as your body adjusts.

Your journey is a challenging one, but you're not alone. Many people have gone through similar experiences and have found ways to cope and thrive. Keep exploring different strategies to manage your symptoms, and don't hesitate to seek professional help when needed. Remember, recovery and adjustment after quitting smoking is a process, and it's okay to seek support along the way.
