Having testicle pain, vomiting, dizziness, stomach pain and weakness. What's wrong?

Hi and wecome to XXXXXXX
Thanks for posting your query.

Your symptoms suggests the possibility of Gastroenteritis, Food poisoning or peptic ulcer disease. Kindly don't worry as there nothing seems to be serious.

You can follow some dietary modifications for relief:
1.) Drink plenty of water and other fluids.
2.) Gradually introduce easy to digest foods, such as rice, bananas and potatoes.
3.) Don't take Dairy Products, Ice creams, sodas.
4.) Make sure you get plenty of rest.
5.) Monitor your temperature regularly.
6.) Medicines such as Loperamide (Imodium) and Bismuth Subsalicylate (Pepto-Bismol), Domperidone and antacids like tums can help relieve symptoms but should be taken under medical supervision.
It will take some time for your body to respond to the Medications.

If there is no relief in next two days, then get yourself examined by your primary physician so that he can do a Stool Culture if necessary along with Blood and Urine work up, so that the causative organism can be isolated and appropriate antibiotics can be prescribed.

Hope this will help you. Please do write back if you have any additional concerns.
Please accept my answer in case you do not have further queries.

Wishing you good health...

Regards.
Dr Saurabh Gupta.
