Hi my name is James Stevens. About 3 weeks ago after a arm/chest workout my chest was in pain. I rested for 6 days before doing any physical activity as a football player. While I was resting I noticed my upper back began to feel sore and tight as my chest started feeling better from icing it. Before going back to football practice I made sure nothing was hurting anymore. My chest and upper back felt fine during and after practice mon-Thursday. Then Friday at school which was no practice that day I felt just a fraction of the pain in the left side of my chest. I iced it when I got home and it went away and felt fine all weekend. The constant issue that hasn t changed however is the tightness I feel in my back and chest. My upper back cracks a lot with deep breaths. It s currently football season I ve only practiced but I have not worked out in 3 weeks. I ve had injures before and I know my body well. This doesn t feel like something that i can t continue playing with its not that bad but i would like to know if anyone has heard of this before and what I can expect. I m only 16 so i doubt its arthritis even though it is possible. I will also like to note that my posture is not the very good and I m currently working on that. Thanks for your time and help and hopefully someone can help me with answers
