Scalloped tongue. Could anyone please give me information with regard to this? I am Hypo and taking 50mcgs T4 and 30mcgs of T3. I have read that this can mean sleep apnea, spleen, grinding teeth, excess fluid, water retention, or quite simply low thyroid. I do not feel better with Meds, and the scalloped tongue is not getting better. Would be grateful for any feedback. Many thanks. Marmaris.
