I'm actively hunting for a solution to my auto immune situation, I'm Hashimoto, have a few allegies for which I take anti histamine pill most days and arthritis in my fingers. I take a T4+ T3 combination after many years of Just T4 Levothyrox. I live in France and we have Just had a recent scandal aboutisse New version of Levo (excipient changed From lactose to another product) which caused many adverse effects and symptoms among patients, some stress related, factor Placebo. In any case I decided to change as I was myself suffering from Bad Brain Fog and a few other symptôms. I Now take the T4+3 Eurthyral from Sanofi. Much improvement and no regrets about adding T 3, however my arthritis in my hands is really painful and swollen. I suppose lactose excipient is partly to blame. I'm on a Gluten and lactose free diet for 10 months Now. Any suggestions would be really helpful.
