First of all, I apologize for my English deficiencies (I am international student). So, I am 28 y.o., with hypothyroidism since I was 25, and I am taking 75 mg of Eutirox daily, which is a European levothiroxine brand. In March 2009 I was diagnosted with ADHD and started taking Adderall (15 mg, then 20 and two weeks ago a changed to 25 mg). The problem is that in the last ten days, more or less, I started feeling a lump in my throat, and I in panic, since I'm thinking the worst scenario (I have lost my father last October for pancreatic cancer, and since then, I have become a bit hypochondriac). I had my blood test 2 weeks ago, and everything was fine, but the sense of the lump is making me crazy. The Uni health center referred me to a endocrinologist, I'll go next week. In the meantime, I just wanted to know if anybody has the same experience...it is really frustrating, and I am scared it could be a tumor.
