Hi, I Also Have A Lump At The Back Of

Hi,
I also have a lump at the back of my neck. I have been suffering from back and shoulder pain. I 've been guessing if my bad posture causes it, during childhood I tend to slouch during classes and now that I am working I would try to sit up straight but after 3-5 mins I'll feel strain on my back again and return to slouch. The more i gain weight, the bigger it becomes and it's shameful so I tend to hide it and avoid wearing back showing tops/clothes and even avoid having a short hair. I've had my xray on the neck bone which showed my upper spine is slightly bended go the front. The doctor only prescribed me with pain reliever for back but it will not help me get rid of the lump. Please help me, it would like to know how to correct it, if it's should be removed by surgical operation or by bone rehabilitation or even chiropractic procedures.
