MILLION TESTS NO ANSWERS :(

Hello everyone,

I am new to this site and it seems a great way to help me get answers or talk to people with similar issues!

I posted in another forum, I had open surgery on my left shoulder last week to remove a crap load of calcium, hurts like hell, so much pain but the drugs are helping!

How did I get this? where did it come from, i never had an accident nor fell, i seem to have a million issues with my body and i am only just turned 34. I will name a few below, if you have anything similar please reply:

went to hospital 2010 with severe chest pain, was told i had pleurisy in my chest with fluid in the lung , I do smoke but only about 10 per day (need to quit)
anyway
I kept getting pleurisy, month after month chest pain, saw a great lung DR who done lots of tests, ANCA test come back positive for auto-immune disease., thyroids and rheumatoid also came back positive
I had a lung function test that came back very low 53% most people are around 80-90% and for my age that's low.
I had problems walking, I would get intense pain in my calfs, out of breath easily and just generally unwell.

later found out I have carpel tunnel in both wrists, calcium in shoulder, which i just had the operation (PAIN IS NO WORD TO DESCRIBE HOW AWFUL THIS IS)

I had a lung biopsy in 2011 and was diagnosed with churg strauss, I was on very high doses of prednisone, for 4 months this did not help at all, i put on so much weight and there was no improvement,
they decided I did not have churg strauss and now i am at a loss. they have o idea whats wrong with me, still get the chest pain, still feeling bla!

can anyone shed some light, have you gone through something similar??/
