Asthmatic with sharp chest pain

[ERluvr]

Recently I had a spontaneous pneumothorax. I was only in the 6th grade and was 12 years old. I was treated with only an oxygen mask and was hospitalized for five days. I have mod. severe asthma and am on pulmicort and serevent for management of my attacks. I am now 15 years old and have been experiencing good management of my asthma with very few attacks during the year; however, I've been experiencing some chest pain. It is a sharp stabbing pain that worsens when I breathe in. It's on the left side around the area of the heart. I experienced it a year ago and visited my doctor because it got to the point where I had to take very shallow breaths and stop all activity until it went away. It increased in its frequency over time, occuring every few minutes. He diagnosed it as a case of pleurodynia (sp?) that would go away on it's own. It did pass in a couple of weeks, but recently I've been experiencing it again. The same type of sharp, stabbing pain, and it has become increasingly frequent. I've now had it for at least two weeks. Someone once mentioned it's possible relation to my previous pneumothorax. Is it possible that this is some sort of "effect" from it? I can't find any pattern in it either. It doesn't occur after eating certain foods or exercising. I'm not overweight and am in fairly good shape. I have no history of heartburn or gastrointestinal problems. It occurs completely at random and can last anywhere from a few seconds to thirty minutes. Any help would be GREATLY appreciated!!! Thank you so much!

You should have a chest x-ray.  That may reveal the cause, which could even be a recurrent pneumothorax.

A pain that worsens with breathing can be due to either a problem in the:  
muscles, including the ribs, cartilage, or nerves; or
pleura, that is the lining of the inner chest wall and the lungs.
It is possible that this pain is related to the pneumothorax.  It is also possible that this pain is coming from the chest wall and has nothing to do with the pneumothorax.  If your chest is not sore when touched at the area where you feel the pain, it is probably coming from irritation of the pleura or a nerve that runs along the lower edge of the ribs, called the intercostal nerves.

If your chest is sore when touched at the area where you feel the pain, it is almost certainly muscular.  Try to remember if you may have strained your chest with exercise or had a blow to your chest.  If the chest x-ray is clear, you and your doctor might want to consider some limitation of physical activity, especially exercise that involves the chest.  Also a trial of an anti-inflammatory medicine, such as ibuprofen, may help.

Thank you for your help!
Recently the pain has kind of changed to a subtle pain, but it's somewhat sharp - I can pinpoint it's location. I'm not experiencing any tenderness in the area, it doesn't seem to be muscular at all. I was going to go to the doctor, but it seemed like it was kind of getting better with the change of pain and all. Do you think it's necessary to see someone about it? It's not that bad, but I know it's not normal.
Thanks again for your reply!

Also...one quick thing I forgot to mention. Recently I've developed headaches, no other symptoms, nothing sinus related, just a sort or pressure/ache. I've been getting them every single day for the past week. I have no history of headaches or problems like this. Do you think this has any correlation to the chest pain?
Once again, thank you for you help. I truly appreciate your replies and advice!
