I began 50 mg Toprol XL 2 years ago then reduced to 25 mg when palps and blood pressure normalized. Had trouble sleeping. Back in August, I began taking the generic version Metoprolol. One day I couldn't feel my index finger and thumb on right hand and immediate began to worry. I also began feeling depressed and was having terrible panic attacks. Sleeping was non-existent. Also, my chest felt as if it was on fire. Throat closed up and had difficulty breathing. Went to Walgreens nurse and she looked at me funny and said it was allergies to try Claritin and Flonase. DID NOT HELP! Went to the Dr. and he too chalked that up to allergies and gave me a shot. That relieved the breathing symptoms but nothing else. He told me numbness was tendonitis and gave me a "pretty brace." Numbness and tingling did not improve in fact went into other arm which caused me alarm. I went to chiropractor for help...nice massages but still numbness! Then my hands and feet started going cold...I'd had it. Went back to Dr and he put me on Xanax for panic attacks, told me I was depressed and need to see a psychiatrist for mood altering meds. I was ready to slug him! The numbness and tingling are insane! The Dr. to appease me switched me back to Toprol XL...no relief then tried Atenolol. The thing is for a few days while the insurance was figuring out what to pay for, I didn't take meds and began improving. Tried Atenolol and symptoms came right back. Called Dr and was told to just stop altogether...no weaning. Terrible tightness in chest could not breathe...miserable and scary. The next day I got a little better. Sleep improved somewhat but still having trouble with muscles tingling in feet up to knees and muscle cramping in right calve and for arms. Wondering how long this stuff stays in system. Seems to me I should be done...I have been off 17 days and am looking for relief for muscles symptoms...also looking for new Dr...anyone out there know how long this stuff hangs out in your muscles and stuff?????
