This is related to Perimenopause. I am a 44 years old. For the past 2 months I have been experiencing some symptoms such as leg weakness, shakiness in legs, which has somewhat subsided, trembling in the legs--which seems to stem from high stress. I also have a pins and needles sensation in my limbs and feet. I have also had sudden warming sensations with face redness and some panic attacks out of the blue. My period last month was light and this month it was normal. I was calmer when I had my period this month. My threshold for anxiety has been lower. I have read that magnesium and/or B12 deficiencies can cause leg shakes and trembles. Diabetes has been ruled out. Any suggestions would be helpful.
