Hello Doctor, I have been having H pylory kit with mecobalamin injection, lycome 12, doxycyclin e and lactic acid bacillus capsules, and rosuvastatin tables 10 mg. since last 7 days. After having pills I have a severe pain in my chest, legs, elbow, & shoulder. I m very much worried about that. Kindly help me in this regard & let me know weather it is a general side effect of the drug or there is something serious ? Waiting for your fruitful reply.
