Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. By your history and description, possibility of viral gastroenteritis is more likely in your case. This kind of viral infection can cause body ache, muscle pain etc. Usually these symptoms are self limiting in 1-2 weeks. But you can take simple painkiller like paracetamol or Ibuprofen if your pain is persistent or more. Along with painkiller, you should drink plenty of fluids orally and keep yourself hydrated. You can also apply warm water pad on affected areas for better symptomatic relief. Hope I have answered your query. Let me know if I can assist you further.
