So I read your post and have been dealing with this insane issue for a week now. I am done with this thing. I went to the doctor as soon as I noticed a lil discomfort as I knew this wasnt normal. He gave me antibotics. I was hopefull. Nope... swelling went down a lil and as soon as the last day for antibotics was done swelling right back up.
So reading your post made me super excited. I had started putting tea tree on it as I feel that heals all. I went and started the Witch Hazel, Lavender, and Tea Tree mixture today as well as a salt bath and some Silica in my water. So I hope I am as lucky as you are and to have this P.I.T.A. cyst be gone!
