I was prescribed Omeprazole after having Bariatric surgery (the sleeve). Three days after taking it I woke up with a sore neck.. The next day the pain and soreness was in my shoulders and then upper back. I could hardly lift my right arm..I did not have any shortness of breath.. I was sent to the ER to be checked for blood clots, none were found so I was told to check with my back dr and to continue my medication. I have an appt to see back dr next week..
