Sudden numbness in entire body.

I was diagnosed with acute pneumothorax last year in april. An ICT tube insertion procedure was carried out. A tube was kept for two days and then removed. It got cured. But ever since, I keep getting random pains while breathing. Sometimes at night, I feel breathlessness and sudden feeling on numbness in my entire body (starting from chest area, then neck and head, lastly arms & legs). Then I develop a sudden headache which lasts for about an hour. Also, considerable pain in chest area where operated for pneumothorax. This all lasts for about 1-2 hours and gets cured after someone rubs my palms for blood circulation. Followed by weakness the next 1-2 days. Though the frequency of numbness episodes is less (once every 5 months). Is it normal after one and half year of this procedure? Or should I be concerned?
