### input:
I have hand tremor since last 5 yearsAnd since last 2 year ..I am getting severe pain in my entire body...I am suffering from different kinds of severe pain like burning, numbness, tingling in different parts of right side of the body from head to feet.Sometimes it happens in the left side as well.Sometimes I get the pain throughout the body but sometimes it is at particular parts like in the nerve from the ring finger to the wrist, just below the elbow, in the shoulder, right cheek, near the right ear,below the right ear at the neck, right side of the chest, in the waist, thigh joint, knee, and nerve from the finger of the feet. I feel numbness in one nerve from the knee to the feet. All these pain makes me weaker and causes fever almost every night.(The temp remains normal or low temperature nearly 97.5-97.8)The pain gets more acute with more physical stress. Any pressure in hand or leg increases the numbness leading to pins and needles. Sitting at a particular position increases the burning sensation and cramps at the back.I have hand tremor since last 5 years. But it was not causing much problem to me. But because of all these pain and weakness the tremor has also increased.Feel nauseatic normally in the morning because of Low BP(90/60)

HIT hank for choosing ChatDoctorAs usual you also have not mentioned here your age and sex, any way here is the answer (May not be much helpful). This could be essential tremor, but need to be differentiated with Parkinson's disease, this not a low blood pressure, it is your idea that low blood pressure induces the vomiting and nausea, in case of low blood pressure first symptom would be syncope, hope this will help you a lot Have nice day.
