What could cause my heart to beat faster, nose get blocked, feel headache, pain in shoulders, hands&legs shaking, sweats?

"Adrenalin" A surge in blood level of Epinephrine or norepinephrine can cause all these symptoms. Assuming you are not abusing stimulant drugs, the statistically most common condition resulting in this condition is a panic attack. Also this may be an exaggerated response to early menopause. See your gynecologist.
