Dear welcome to hcm and thanks for choosing us.
I have understood your problem. According to me there are following possibilities in your case
1 excessive fatigue of travel
2
dehydration (yellow urine and weakness)
3 there is some element of food
poisoning too(nausea)
4 it could be
viral hepatitis too (nausea, yellow urine, fever and fatigue)
There is no chance of
pregnancy if you have sex during your periods.
I treat my patients in following ways
Basic health assessment like blood pressure check up
Blood work up for liver function,
haemoglobin levels, wbc count etc
You will require antacids, anti vomiting tablets, vitamin supplements
Rest of the treatment will depend on investigations reports like in case of food poisoning you will require a course of antibiotics, in case of viral hepatitis you will require rest, light diet, liver enzymes, etc.
Meanwhile keep taking plenty of water.
I hope my reply will help you. Please write to us for follow up queries. I wish you rapid recovery. Kindly write a feedback. Thanks.
