I m not in pain at all but they are irritatingly regular and are usualy when im sitting or lying. I dont smoke or drink and I m 36 and attend the gym 5 times a week. Please can you let me know what it could be and how to relieve it. Thank you  <response>: Hi Thanks for your query and Welcome to Chat Doctor. I am Chat Doctor. Such symptoms can be due to Muscle articulations as a result of muscular fatigue since you have been regularly doing Gym. Also, a neurology opinion needs to be done to rule any neurological cause for your symptoms. Sometimes these symptoms can also be due to a vascular cause, although it is rare. So in my opinion kindly get a Neurophyisician consultation done so that required investigations and evaluation can be done. Do not hesitate to contact me if you need any further assistanceSOS You can also discuss your case and treatment plans with me in a greater detail in a private consultation. Thanks Regards
