POLYMYOSITIS and Sjogren's Syndrome

I have been diagnosis with both. I don't know what is happening to me. I have dry mouth than during day a sticky mucus. I thought it came with what I had. Then I had a small lump show up on my left side of face. I thought it was a pimple It drains a sticky mucus.  I had it removed 2x times so far.  I have developed a pimple or 2 in my left ear which has sticky fluid in it.  I wash my hands after touching either one and it is slimy  With all 3 different things this happen. It is all on my left side of face.  I am also numb on L side mouth especially chin and Left side of face. 

     I also have been getting hang nails then hard skin around fingernail with skin 

peeling I don't know what else is going to go wrong.

     My back pain is so bad I can't stand in the morning when I try and get out of bed, Yes I have 2 crushed dish absolutely crushing my spinal cord on L3 and L4.  I agree that maybe a sperate thing  Everything going on Is this normal.

     I understand SS has many things are all these things related?
