I am 48 years old female. I had acidity on Monday which was accompanied by severe headache and vomiting. This happens often but was very severe this time. I was given 2 injection to relive both the problems. But after that day, I am having a constant sick feeling like heavy ness in head, pull in neck area, abdomen and back. I am also feeling a lack of energy even after taken full rest. Please suggest what can I do?
