Your symptoms require a multi-specialty approach. For your sinus issues, nasal blockage, and tinnitus, consult an ENT specialist; they may prescribe nasal corticosteroids. For your LA Grade B oesophagitis, a Gastroenterologist will likely recommend proton pump inhibitors (PPIs) and dietary adjustments. For irregular periods, please see a Gynecologist to evaluate your hormone levels. Finally, your bone pain and limb numbness warrant a visit to a General Physician or Neurologist to test your Vitamin D, B12, and thyroid levels. Please avoid self-medicating until these specialists evaluate you.

For Vitamin D and B12 deficiencies, you require targeted supplementation. Typically, doctors prescribe a weekly high-dose Vitamin D3 supplement (such as 60,000 IU) for 8 weeks, alongside daily oral Methylcobalamin (Vitamin B12) tablets or injections.\n\nYour joint pain and cracking can be worsened by these deficiencies, which affect bone, muscle, and cartilage health. However, painful joint cracking also warrants a physical evaluation to rule out wear-and-tear issues like osteoarthritis. Please consult your doctor to get a precise prescription tailored to your exact blood levels. They may also recommend temporary pain relief, calcium supplements, and joint-strengthening exercises.

Nerve pressure in the wrist or neck, excessive use during pregnancy, vitamin insufficiency, or swelling following pregnancy can all cause numbness in the middle and ring fingers. Repeated hand positions might also cause nerve strain because you are nursing and taking care of a 5-month-old. When at all feasible, try resting the hand; avoid bending the wrist for extended periods of time; stretch gently; and consume wholesome meals that are high in calcium, iron, and vitamin B12. Please contact a doctor or dermatologist if there is a rash, colour change, pain, or spreading skin changes. The "guilty skin type" you referenced is not quite evident from the letter, and I am unable to view the photo here. If the numbness worsens, results in weakness, or interferes with everyday tasks, get medical help as soon as possible.
