<s>[INST] Just back from Punta Cana 2 days ago and I started feeling sick the last 2 days while I was there.  Since, it isnt constant but it persists, especially in the evenings:  body ach, kidneys dont feel good, cramps, sweating, diarrhea, feeling that I want to vomit, no energy.  Im not used to that at all.  Im afraid I might have malaria even though I never left the resort.  I have a prescription in my hands:  novo chloroquine, I know I should have started to take it prior to departure but I elected not too ...  So would it be smart to start using it as of now? [/INST] Hi, dairy have gone through your question. I can understand your concern. You have body ache, cramps, diarrhea, nausea and weakness. You may have malaria, viral fever or some other infection. You should go for complete blood count and test for malaria parasite. If your tests for malaria parasites comes positive then you should take treatment. Otherwise antimalarial treatment will not help. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have any doubts then contact me at bit.ly/ Chat Doctor.
