An evening fever of around 100°F with one-sided pain from the back to the knee may be due to a viral infection causing body aches, muscle inflammation, or sometimes nerve-related pain such as sciatica that becomes more noticeable during fever. For relief, you can take Paracetamol, rest well, and stay well hydrated. If the symptoms persist beyond 3-4 days, become severe, or are associated with weakness, numbness, or difficulty walking, it is important to consult a doctor. Your doctor may advise basic investigations such as blood tests (to rule out infections) and, if needed, imaging like an X-ray or MRI to check for nerve or spine-related causes, and then guide further treatment accordingly.

Lower abdominal pain can have many causes, such as gas, constipation, urinary infection, menstrual issues (in women), or intestinal infection. For mild pain, try drinking plenty of fluids, eating light meals, and avoiding spicy or heavy foods. A mild antispasmodic or paracetamol may help if suitable for you. However, consult a doctor for proper examination and tests to identify the exact cause and receive appropriate treatment.

A fever starting at 102 degrees Fahrenheit and coming down to around 100 degrees Fahrenheit after paracetamol is quite common, especially in viral infections like flu or a simple viral fever. It shows that your body is responding and the medicine is helping control the temperature, even if it has not gone away completely yet. Paracetamol can be continued only as advised by your doctor, usually when the fever is uncomfortable or above a certain level. It mainly gives relief but does not treat the underlying cause, so a mild fever may still persist for a couple of days. For now, take proper rest, drink plenty of fluids, and eat light food. Keep monitoring your temperature and avoid overexertion. Most viral fevers improve within 2?3 days. If the fever continues beyond this, becomes very high again, or you develop symptoms like severe headache, vomiting, rash, or weakness, it is important to consult a doctor for further evaluation.

Please see a doctor soon to check for a chest infection and ensure your symptoms are not affecting your pregnancy. You can safely use paracetamol for your headache and try saline nasal drops or steam inhalation for congestion. Do not use over-the-counter cough syrups or decongestants unless prescribed by your doctor, as some may not be safe during pregnancy.
