you say your spine is swollen and has a huge buldge with extreme weekness and pain. you didnot mention in which part of the spine you have problem(cervical / thoracic / lumbar) probably the pain and bulging sugeests some inflamatory kind of pathology like abscess / tuberculosis
i.e potts spine. do youhave history of fever with weight loss
with loss of appetite and did you ever had history of spinal trauma
as this may cause subluxation/ fracture of vertebra.collar bone pain
may also be due to trauma. first my advice is to wear a cervical collar
, and analgesics like tramdol and paracetomal along with bed rest. get an x-ray and MRI spine done to localise the pathology.
