Hi, For the past two days, I have been noticing yellow mucus when I spit for the first time in the morning. Last month, I had a complete blood test done, and the only abnormality was slightly elevated lymphocytes. I have Gilbert syndrome and vitamin B12 deficiency, while my vitamin D levels are normal. I have also been experiencing pain in both knees for the past 15 days. I got an Xray done, but the doctor said everything looks normal. I am currently taking Shelcal HD and A to Z daily. Could this indicate any inflammation or infection in my body? Is yellow mucus in the first spit normal?

Yellow mucus in the morning can be normal, often due to mild nasal drip or throat clearing while sleeping. It does not always indicate infection if there is no fever or worsening symptoms. Slightly high lymphocytes are common and not concerning alone. For knee pain, continue light stretching and use supportive footwear. If knee pain persists, check Vitamin D, B12 and uric acid levels if not done recently. Stay hydrated and continue your current supplements.

What is MCH in a blood test?

Answered by Apollo Doctors

Hi, my blood report says predominantly normocytic normochromic with macrocytes and ovalocytes. What does it mean and what could be the cause? What is its effect and how can it be rectified?

I got my period after almost three months, on 15th July. Since then, I have been experiencing an electrical chill sensation on my scalp and tingling on my face below the eyebrows and lips. I consulted a neurosurgeon 8 days ago, described these symptoms, and was prescribed Nuhenz for 15 days with advice to follow up afterward. The electrical chill and tingling have now reduced by 50 to 60 percent. Recently, due to cold weather, I kept cotton in my ears for three days continuously, and now I hear a ringing sound in my left ear when in a quiet space. Additional notes: I had gum bleeding in the front teeth and visited a dentist, who found inflammation and cleaned my teeth. My blood report shows very low Vitamin D and slightly higher than normal TSH levels. Kindly let me know what could be causing these symptoms and what I should do next.
