My advice is to seek out a dermatologist (preferably one with prior military experience like a retired military Dr.). Have the Dr. give you an examination and if the condition is no longer present have the Dr. draft a letter stating so and submit it to DoDMERB. Also you need to draft a letter and have it ready to submit stating that your previous eczema was very mild and never caused you any issues. As far as a waiver goes it’s anybody's guess... The AF seems to have the biggest issue when it comes to managing their officer corps needs. As evidenced by them releasing some AFROTC cadets from their commitment to leave prior to commissioning, giving some the option to go guard but then offering massive bonuses for some to stay and others to retrain into a different field. I mention this only in that when a service is drawing down, like the Army, a waiver is less likely but with the AF it really is a crap shoot right now. Best of luck.
