Patient's Query

Hello doctor,

I had a blood test recently and my ESR was elevated to 22, while vitamin B12 was low. I have pain in the right armpit and also a pain in the neck.

Hello,

Welcome to icliniq.com.

Your B12 level is low, hence it should be treated with Folic acid tablets and Cyanocobalamin injections.

1. Cyanocobalamin 1000 mcg injections are given intramuscularly for six weeks.

2. ESR (erythrocyte sedimentation rate) can be high in any inflammatory condition.

You have mentioned that you have neck pain and right arm pain. So, a nerve compression or cervical spondylosis needs to be ruled out. For that, a neck X-ray and if needed an MRI are to be done.

3. You can consult an orthopedic surgeon for examination and further work up accordingly if needed.

Take care. I hope your concern is solved.

Patient's Query

Thank you doctor,

The pain is in the underarm and at the front of the neck.

Hello,

Welcome back to icliniq.com.

I understood the neck pain to be at the cervical region.

If it is at the front, we do not need to consider cervical spondylosis-like lesion. If there is associated chest pain, cough, dyspnea, or gastritis, let me know about it. This type of a pain can be a muscular strain as well, in which case Ibuprofen can be prescribed for five days. A warm compress will also be beneficial. If an improvement is not seen, then an X-ray and USG can be planned.

I want to add that Cyanocobalamin injection is given once a week for six weeks. So, a total of six to eight injections is needed for treating the vitamin B12 deficiency.

Take care. Let me know if you have further queries.

Patient's Query

Thank you doctor,

I have an acidity problem which resulted in gastritis. I have been treated for it. I have abdominal problems though. I also have to take multiple deep breaths, so that my lungs can get enough air. I feel very weak. My vision is poor as my pressure is high. And, I do have cervical spondylitis.

Hello,

Welcome back to icliniq.com.

At this moment, I am giving you a further description regarding your case.

1. For acidity and gastritis which drug have you been prescribed? For a gastric problem, Pantoprazole is prescribed for two weeks. If there is no improvement, then you will need an antibiotic course. If you still have the problem, then anultrasonography and urea breath tests are done to rule out H.pylori.

2. Regarding your breathing trouble, let me know if you have an anxiety issue. If there is a lot of stress and anxiety, there is usually a complaint such as yours. If there is no stress, then I advise you to get investigated with a chest X-ray and pulmonary function test (PFT).

3. Your fatigue and weakness could be from B12 deficiency. If weakness persists after taking B12 injections, then a further work up needs to be done with serum calcium, serum sodium estimation, serum TSH, serum T4, SGPT(serum glutamic pyruvic transaminase), SGOT (serum glutamic oxaloacetic transaminase), urea, and creatinine. Overexertion, stress, lack of exercise, and less sleep also leads to weakness.

4. You have mentioned having cervical spondylitis for which cervical spine MRI was done, and if the arm pit pain is related to it, then Amitryptillin or Pregabalin can be prescribed.

5. Conservative therapy, muscle relaxants, Ibuprofen, and physiotherapy are some other modes of management for cervical spondylitis.

6. For the vision problem, check for hypertension and diabetes. A direct ophthalmoscopy examination is needed.

Take care. Hope your concern solved. Consult your physician for a review and discuss all these points.

Patient's Query

Hello doctor,

Thanks for your reply. Could my vitamin B12 and D deficiency be the reason for me to be out of breath? Also, I am taking Vitamin B12 1500 mcg from nearly two months. How much longer do I have to take it? I took two 500 mcg methylcobalamin injections in a gap of three days. Is it alright? I also wanted to ask you whether PPI like Rabeprazole and antibiotics like Penicillin can hinder the vitamin B12 absorption? I am asking because I have been taking Rabeprazole for the last seven months and antibiotics for my fever.

Hello,

Welcome back to icliniq.com.

1. A vitamin B12 deficiency and vitamin D deficiency can lead to tingling and numbness in the hands. In the case of anemia, breathlessness on exertion can occur. So, correct both of this, for an improvement. For vitamin B12 deficiency, take Cyanocobalamin injections 1000 mcg intramuscular once a week for eight weeks.

2. Long term use of proton pump inhibitor can affect the absorption of vitamin B12. Hence an injudicious use of Rabeprazole should be avoided.

3. For vitamin D deficiency, you might have been prescribed cholecalciferol sachet 60000 IU once a week for six to eight weeks.

4. Only if the cause for your fever is a bacterial infection, an antibiotic should be prescribed.

Take care. I hope this will help you. Refer to a physician for examination and discuss your case.
