Lung pain after surgery for collapsed lung (spontaneous pnuemothorax)?

I was in the hospital for a week with a collapsed lung (spontaneous pnuemothorax), and they were able to re-inflate my lung by using a chest tube, however, my lung went down again a day later while I was still in the hospital, so they decided to use surgery to correct the problem. During the surgery I was put to sleep, and the doctors did some stapling on my lung I believe and also used talcom powder to make my lung stick to my chest. Idk what type of procedure exactly it was. I am 17, tall and slender (one cause of my collapsed lung I had). But now, when I breathe in heavy it hurts in the right of my chest, where they fixed the lung. I was wondering if it will just be like that for a while, or if my lung could be collapsing again. It's been about 3 weeks since my surgery, and I went to the doctor about a week ago to get a check up on it. He told me my lung looked fine under the x-ray and I should never have anymore problems with it, to come back in a month, and that I can start skateboarding again next week. The pain is only there when I take pretty deep breathes, and is sharp. I know when it collapsed, the pain was constant, so that is why I believe it's just me being sore from the surgery. If you need any more information please let me know. I can not afford to go to the doctor about it right now, so please don't answer with "Go to your doctor" or "Get it checked out by a professional". From my surgery and days in the hospital I'm sure you can understand why I can not. Thanks, any help is HIGHLY appreciated.
