Discomfort in the lower back and testicles after masturbation may occur due to muscle tension or congestion in the pelvic area, which is often temporary. Avoiding frequent or vigorous masturbation, resting, gentle stretching, applying a warm compress, and staying well hydrated can help ease the pain. If the discomfort persists or worsens, consult a doctor to rule out any underlying issue.

Significant pain during sex is not normal and may occur due to dryness, irritation, a small tear, or an underlying problem. Stop sexual activity for now, use good lubrication, and avoid forcing penetration. If the pain is severe or persistent, or if you notice any injury or swelling, see a doctor as soon as possible for a proper check-up.

Since you are already taking moxifloxacin, Ocupol, cetirizine, and Hifenac, a difference in how your eyes respond is quite common but requires attention. One eye may simply have a more stubborn infection or inflammation. Please continue your medications as prescribed and contact your ophthalmologist for a quick follow-up to evaluate your left eye. In the meantime, avoid rubbing your eyes and wash your hands frequently to protect your healing right eye.

Your CRP level of 3 is reassuringly low, indicating minimal active inflammation, while the LDH of 560 is slightly elevated, which is common as your tissues recover. For weakness, Shelcal M and Vitamin D are excellent for rebuilding your strength. However, Hifenac P (aceclofenac/paracetamol) and Protera D (pantoprazole/domperidone) are for pain and acidity; you should avoid taking them daily unless you actively experience those symptoms. Cimium 500 mg (calcium dobesilate) supports circulation but should be reviewed by your physician. Focus on rest, good nutrition, and consult your doctor to safely tailor these medications.

While mild headaches and body aches can sometimes occur during your period, experiencing a fever, cough, and cold is not typical and suggests a viral infection coinciding with your cycle. Hifenac-P, which contains aceclofenac and paracetamol, is safe to take and will help reduce your fever, headache, and body aches. Please ensure you take it after food to prevent stomach irritation. Since it will not cure the cold or cough, I recommend resting, staying well-hydrated, and consulting a healthcare professional if your symptoms do not improve within a few days.

Phexin (cephalexin) is generally safe to take while breastfeeding, though you should monitor your baby for any mild diarrhea. However, Hifenac P contains aceclofenac and paracetamol; while paracetamol is safe, aceclofenac is not recommended while breastfeeding. I suggest using plain paracetamol or ibuprofen for pain relief instead. Since the boil is leaking, please have a doctor physically examine it. They can safely clean it, confirm the correct dosage of cephalexin, and ensure you and your baby stay safe and comfortable.
