Autoimmune symptoms can have commonalities to withdrawl but they tend to be specific to the part of the body they affect - for example, with rheumatoid arthritis, joint pain and fatigue are generally present and with hyperthyroidism such as Grave's disease (hyperthyroidism), increased heart rate, frequent bowel movements, anxiety, to name a few are common. So to answer your question, yes, withdrawl symptoms can overlap withdrawl symptoms but an autoimmune work-up should be specific to the suspected body system it may be affecting.
