Hi. I ve had chronic shivering/judder type of symptoms since i ve been young. Everyone around me notices that when my hands , or arms are active, for instance when passing lightweight (not even heavy) objects to someone, my hands will tremble. I notice this in my legs too. It often always occurs when my body is active, even slight gentle movements cause it. When i was younger i did not worry so much & assumed i may overcome it. However, i m 25 now and it effects me socially as well. I want to find out whether it s something associated with my nerves internally, or if it s psychological. I m a healthy 25 years of age female individial, don t smoke , don t drink, healthy weight, i ve never had any other health issues. I have a fairly healthy diet too. Take vitamins sometimes as well. I don t drink coffee, just tea. If you can provide any possible directions, or ideas for me to consider, i will appreciate it

Hi, Welcome to Chat Doctor forum. I understand your concern. Fine tremors are associated with few medical conditions such as nervousness, thyroid overactive state, vitamin deficiencies especially vitamin B12 and rarely neurological condition.  If you haven't yet seen a doctor for this problem, I would encourage you to visit your physician. A little blood test will help us to know about your problem completely. We can then manage your condition accordingly. The test performed would include tests for vitamin deficiency, thyroid levels, other hormone assessment and neurological evaluation. A small dose of beta blockers can be prescribed to treat tremors and improve your quality of life. Hope this answer is informative.  Wish you good health. Regards
