side effects morphine two morphine shots 4 MG ea

I had two morphine shots 4MG each - about 3 weeks ago for chest pain. Heart problem

was ruled out. Possible stomach problem. Am still taking tests.

I have not been feeling well since going to the emergency room. Very tired all the time,

get very hot and then cold chills. Have no appetite and have lost about 6 lbs in three weeks.

Would it be possible that my feeling the way I do is a side effect from the morphine. It has

been three weeks now.

Thank you
