internet and self diagnosis

So not sure if you remember but early in January I took a trip to my "in laws" and while loading the car I tried to swing my super heavy school bag onto my back and my left shoulder protested furiously. Well fast forward to April, I am still super sore in it, I can not really use my arm that much, I can hardly grab my seat belt to fasten it since that motion gives me pain, I also wake up a lot to readjust myself cause my favorite sleeping position is having my left arm under my head and that is freaking painful. I am always postponing going to the doctor but guess I really should go have it checked out since I guess it is not fixing it self cause it has been 3 whole months since it happend. I think I might have torn something in my shoulder and this is what I found when I googled the symptoms.


Injuries to the tissue rim surrounding the shoulder socket can occur from acute trauma or repetitive shoulder motion. Examples of traumatic injury include:

• Falling on an outstretched arm
• A direct blow to the shoulder
• A sudden pull, such as when trying to lift a heavy object CHECK
• A violent overhead reach, such as when trying to stop a fall or slide

The symptoms of a tear in the shoulder socket rim are very similar to those of other shoulder injuries. Symptoms include

• Pain, usually with overhead activities CHECK
• Catching, locking, popping, or grinding
• Occasional night pain or pain with daily activities CHECK CHECK CHECK
• A sense of instability in the shoulder CHECK
• Decreased range of motion CHECK CHECK CHECK CHECK
• Loss of strength
  
   This should be my motto hahahaha
