For over a week, I've had pain of varying degrees in my upper back between my shoulder blades, closer to my right shoulder. In the morning, it is virtually nonexistent, but as the day goes on it worsens, especially if I sit in or on something without a back on it or bend over to pick something up. Right now, at about 9:45 PM, it's medium and dull to sharp and piercing, with flare-ups of the sharp pain every few seconds (with especially sharp ones every few minutes). The best way I can describe it is that it's like someone has stabbed me in the back and left the knife there, but they pulled it out most of the way, and as the day goes on they push it further in, sometimes pulling it out and stabbing again with more force. I get distracted momentarily from my homework by it. It's impossible for me to sit on the floor or on the edge of my seat without a flare-up. I have trouble finding a position that's comfortable when I go to sleep because the pain won't fade until I fall asleep. I've mentioned it to my dad, but he doesn't want to go to a doctor just for this. I don't want to try pain meds because some of them make me drowsy and I have school and homework that lasts till late. I don't know what to do. I want this pain to be gone. Does anyone have any advice?
