- joint pain that moves from one spot to another
- headaches
- poor concentration
- loss of memory
- digestive disorders like irritable bowel syndrome (IBS)
- chills
- night sweats
- enlarged lymph nodes
There may also be significant alterations in levels of
- irritability,
- mood swings,
- panic attacks,
- anxiety and
- depression.
