Chest & Breathing Problems

My B12 was 118 pg/mL. I received Casinerve Plus (methylcobalamin 1500 mcg IM) in my buttock on Friday evening. From Saturday afternoon, I developed intermittent shortness of breath/air hunger. Last night it became quite severe with chest heaviness. Sometimes when I take repeated deep breaths, I feel dizzy. My SpO₂ and pulse have been normal, and BP has generally been normal, sometimes slightly low. I want to know whether this could be a reaction to the B12 injection or another cause, and whether I should avoid another injection and consider oral B12 or another formulation.

For the last 1 month, I have recurrent throat dryness and irritation with an urge to cough or clear my throat. Coughing gives temporary relief, but the irritation returns. During daytime it happens around 10–12 times, but at night after lying down it becomes much worse, sometimes every 5–10 minutes, making it difficult to sleep. I have allergic rhinitis and regularly stay in an AC room (26°C) with a fan. My AC has not been serviced for a long time. I have also used Foracort 200 inhaler. Could this be due to post-nasal drip/allergy, sinusitis, silent acid reflux/LPR, asthma, or dust/mold from the AC? What tests may be needed to identify the root cause, and what treatment/medicine would be appropriate?

Respected Doctors, Can we use duolin along with Foracort 400 for rescue ie SOS. Are there any side effects.Regards

Sir “I have had breathing problems for about 6 years. When I walk fast or travel, my breathing becomes very rapid, I get very tired, and I develop a severe headache all over my head. Sometimes the headache is so severe that I cannot even move my head. The headache does not go away quickly. Inhalers have not helped much. My basic tests are normal, and my HRCT chest is also normal. Which specialist should I see for this problem, and what further tests may be needed .

Sir, PFT is scheduled at 2 pm so at what time should I take the inhaler or no for that day. Pls guide. Regards

Any suggestion for asthma friendly bp medication or should I continue this? .
