Ana positive strong family history of lupus. Lupus symptoms. Could it be sarcoidosis instead of lupus.

Maybe. ANA positive diseases are related. Diagnosis is based not just on serologic testing, but also on your clinical symptoms. You should be evaluated by a rheumatologist in order to receive an accurate diagnosis and then receive the most appropriate treatment.
Possibly. There is insufficient information in your question to determine whether you have sarcoidosis or not. You should definitely see a doctor if you are not already doing so.
