m experiencing tachycardia, nervousness, anxiety, irritability
and pounding heartbeat. Most recently my
menstrual cycle (last 3 months) have been shorter by several days.
So, here's my question. Can Hashimoto's Thyroiditis cause these times of what I think are hyperthyroid symptoms? If so, how often will it go on for? I feel like I'm swinging back and forth and there are times where I feel totally normal too.
