What Causes Over-abundance Of Eye Mucus?

ive had this problem that started with an over abundenance of mucous in eyes. i now have sores that are on arms. they were small at first. i went to regular MD and was given several different medcations. none helped. went to my Dermatologist ive been seeing for years. he gave me medications after several blood fest. to say the least they did not work either. i call to scheduel another appointment and was told he could no longer treat me. even sent a letter stating he could no longer be my physician but would be happy to send records to another doctor when i find one. i am at my wits end. this has spread to my head, the sores, im speaking of. they have gotten bigger on my arms and im so ashamed with no idea of what to do. my sister moved back to this area a couple of years ago when our mother was sick and passed away. she now has the same problem as i do. she is going to see an infectious disease specialist the end of this month. im going to see doctor that referred her to get appointment also. i guess the reason for asking what this could possible be is because i have no energy at times and want to know if you all have any idea what nthis could be and a cure?
