Hello,
Thank you for asking at HCM.
I went through your son's history and would like to make suggestions for him as follows:
1. It is possible to have nose bleed due to
rhinitis or dry air exposure, especially due to heavy pricking nose. But in general, nose bleeds have no relation with
asthma.
2. If bleeds are minor, moisturizing inner surface of nose by using frequent saline drops would help. Also, putting ice over nose bridge may help during bleeding.
3. If bleeds are major and not stopping, in that case I would suggest you to take him to
pediatrician and get him examined.
4. Please make sure his nails are trimmed so that he cannot injure inner nose membrane subconsciously while itching.
Hope above suggestions will be helpful to you.
Should you have any further query, please feel free to ask at HCM.
Wish your son the best of the health and recovery ahead.
Thank you & Regards.
