question: Hello doctor, I was a healthy, mentally sharp and energized person before. But, for the past 12 years, my brain and body get tired very easily. I am having mental and physical exhaustion and the condition is gradually worsening. I feel drowsy after studying for some time. With this problem, my studies have dropped a lot. I get very easily fatigued by doing just 15% of normal work for this age. My physical work has dropped because of lower limb dragging while walking or standing for some time for the last 10 years. I am also having neck muscles stiffness while seeing up or down and shortness of breath. I feel a sore in my lower back muscles after standing for some time. My eyes get strained while reading or watching television or browsing internet for very less time. I do get excessive sweating and there is a rise of heart rate for below moderate work since 5 years. I am unable to go gym. I fear to do yoga due to shortness of breath, weakness and exhaustion. I also have decreased cognition. Due to the mental and physical exhaustion, I am irritable sometimes. I went to all the best doctors in my place and no one was able to find the disease. Even the psychiatry doctors were also unable to find the cause of these irregular symptoms. As allopathy doctors were unable to diagnose the cause of my symptoms, I have used some over-the-counter ayurveda medicines. Does any ayurveda medicine cause these symptoms after using them for a long time? I am currently on venlafaxine tablet 225mg.
