Hello! I am 24-years old, 5'2'' and approximately 135 lbs. I am perfectly healthy with no prior medical conditions ever in my entire life. The last four or so days I have been experiencing back pain in the upper and lower region. At first it was mild, but now the pain is constant. It isn't a severe pain, but it is quite bothersome. The other thing is I do have a larger chest size for my size. I am about a DD-DDD depending on the bra I wear. I don't want to jump to conclusions, but I read articles where women have experienced back pain due to the weight of their chest. I have lost some weight recently and I don't know if there could be a correlation between the two. My chest does feel heavy and weighed from time and time and otherwise I am quite physically active incorporating bike riding and yoga into my daily routine. If I could get a second opinion I would appreciate it greatly. Thank you!
