Observatory Tremors, low confidence.

Dear Sir/Mam, I have been facing observatory tremors, also if I try to keep my hand stable I couldn't, also fine shaking can be seen, if I remain seated without any back support for few minutes then my whole body starts to move back forth ( small movement but can be observed by other person ). For such reasons I tried to quit caffeine containing beverages and foods. Also I try to meditate in morning but non seems worth helping in my condition. Consulted many doctors and getting different answers from everyone eg. Excess fire of neurons / maybe due to anesthesia which was applied 10 years before while appendix operation / Ignore it / is it making any changes in your lifestyle. I am looking for solution not an irrelevant answer. Please help me understand and diagnose my issue. Thanks Tauseef Khan.
