My sister has sarcoidosis, and I was wandering what are the chances I would have it too. My sister and I share alot of the same symptoms. I have been voicing my concern about all these issues and the only thing I get from my doctor,is oh its nothing your fine. The problem is I do not feel fine,for atleast a year now. I have constant headaches,chest pain,fatigue,pains in my back(upper part),pain on and off generally everywhere on my body,nausea and dizziness.My lymph nodes swell up now and then in my neck and armpits,also I have constant sinus problems,coughing alot and I am now having an issue with my eye. I am researching every course I can to find an answer for all these problems,Just looking for some suggestions about all this. (I have re-posted this here hoping someone would answer,thank you)
