Hello, I am a 53 year old Female. I currently take Crestor 5mg and have for 4 years. I was also diagnosed with Hypothyroidism 4 years ago, which I take Synthroid 0.025mg. I have been experiencing itchy skin, muscle pain, muscle cramping in my feet and legs for months now. Just recently I have been waking up with a dull headache behind my eyes. I have also been battling excema, hair loss, fatique and memory loss which I associate with the Hypothyroidism? I have just starting taking Evening Primrose oil and Flax seed oil and was wondering if these would be safe to take with my current medicines? Im also concerned about the Crestor side effects. Please advise. Thank you.
