Positive ANA and ENA Panel

Hey guys, new to group. I have a question that maybe someone who's been through something similar can help me with. Im a 33 year old Hispanic male. Whole thing started late June of 2018. I noticed a big lump about size of an egg on left side of neck above collarbone. My doc did blood work and sent me to do a ultrasound. I was told blood work came back ok but but radiologist thought lump was lymph node. She then sent me to have CT scan. By this time I had already been feeling a little off at times. I felt tired and was dealing with nausea, headaches, bloating, shoulder pain and so on. She then sent me to a hematologist who in turn did a lot of blood work, x-rays, and another ultrasound. He said he thought lump was a muscle and not lymph node. Whooo, but then he said blood work keeps showing positive ana. He then did a ena panel and came back positive for scleroderma, lupus and rheumatoid arthritis. Wow! So now he sends me to a rheumatologist. A week before appt I got strep throat. It was the worst thing I have ever been through. Every bone in my body hurt so bad for three days and I had a massive headache the whole time. I never ever miss work but I did this time. I explained all this to him. He then said well since you don't have any swelling I don't think you have an auto immune disease. I think you have fibromyalgia. He sent me to do a bone density scan and a lot more blood work. Ill see him in two more weeks. Just wanted to get you guys take on this. Thanks in advance and sorry for bad grammar and punctuation
