I am 23 years old having sedentary lifestyle. From the last 1-2 days my body feels very wierd. Having numbness type in left leg from the knee. Feeling that i will get a heartattack or will die soon.Trembling in body while lifting some normal heavy things. Twitching and numbness occurs when i do activities for a same position for a long time. Some gas trouble also troubles me alot. Recently on Sept-2019 i had undergone several blood test such as
kidney,
liver,cbc,
thyroid,cbc,lipied etc all are in a normal range.
But these symptoms scares me alot and due to this i am not able to focus on careere and studies. Please guide me what to do and whether this symptoms are a dangaerous signal for the body.
