Pain on the right side of the stomach for 2 days can be caused by several factors. It may be due to gas, indigestion, muscle strain, constipation, or an infection in the stomach or intestines. Sometimes, pain on the right side may also be related to the appendix, gallbladder, kidney stones, or liver problems. The exact cause depends on where the pain is located and whether you have other symptoms such as fever, vomiting, loose stools, burning during urination, loss of appetite, or swelling of the abdomen. For mild pain, you can try resting, drinking enough water, and eating light foods such as rice, curd, soup, or bananas. Avoid oily, spicy, and heavy meals for a few days. Do not take painkillers without medical advice, as some medicines may worsen stomach problems. Please see a doctor soon if the pain becomes severe, shifts to the lower right side, is associated with fever or vomiting, or does not improve within a day or two. A physical examination and tests, such as blood tests or an ultrasound, may be needed to identify the exact cause and decide the right treatment.

Since your ultrasound, urinalysis, and endoscopy are clear, we can look at causes related to movement rather than internal organs. Given that the pain occurs with exertion and resolves with rest, possibilities include musculoskeletal issues like an abdominal wall muscle strain, a sports hernia, or Abdominal Cutaneous Nerve Entrapment Syndrome (ACNES). Another condition to consider is Median Arcuate Ligament Syndrome (MALS), which affects blood flow during exercise. I recommend discussing these options with your doctor, who may suggest a targeted physical exam or specialized imaging to help you find relief.

Persistent severe stomach pain and vomiting despite treatment may indicate a serious medical condition that requires urgent attention. You should see your doctor immediately to rule out conditions such as a stomach ulcer, infection, appendicitis, or bowel obstruction. Until you are evaluated, avoid eating or drinking to allow your stomach to rest and prevent worsening of symptoms.

Lower abdominal pain lasting for three days can have many possible causes, including digestive issues (such as constipation or indigestion), urinary tract infection, kidney stones, or, in some cases, conditions like appendicitis or colitis. Because the causes vary widely, the correct treatment depends on a proper medical diagnosis. It is not advisable to self‑medicate, as taking drugs without knowing the cause may mask symptoms or worsen the condition. The safest step is to consult a doctor promptly, who can examine you, run necessary tests, and recommend the appropriate treatment. Seek urgent care if the pain becomes severe, is associated with fever, vomiting, blood in stool or urine, or sudden worsening.

Since Eno, Pudin Hara, and the dicyclomine (Cyclopam) tablet have not helped, please avoid taking more medications at home. A ketogenic diet can sometimes stress your gallbladder or pancreas, which might cause persistent mid-stomach pain. Please rest and sip plain water. Because this pain is not responding to standard treatments, it is very important to see a doctor for a physical evaluation today to find the exact cause and get the right relief. Please seek immediate care if you develop vomiting, fever, or worsening pain.

I would generally advise avoiding Cyclopam (which contains dicyclomine and paracetamol) while breastfeeding. Dicyclomine can pass into breast milk and may cause side effects in infants, such as sleepiness or breathing difficulties, and it can also decrease your milk supply. Please don't worry?there are much safer options available to help you feel better. I highly recommend speaking with your doctor to find a breastfeeding-safe alternative, such as plain paracetamol, depending on the symptoms you are experiencing.
