Thanks for your question on Healthcare Magic.
I can understand your concern.
He is mostly having
costochondritis (inflammation of rib
cartilage).
Warm feeling on touch is due to inflamed ribs and cartilage.
So ask him to follow these steps for better symptomatic relief in costochondritis.
1. Avoid movements causing pain.
2. Avoid bad postures in sleep.
3. Avoid heavyweight lifting and strenuous exercise.
4. Take painkiller and anti inflammatory drugs.
5. Sit with proper back and chest support.
6. Apply ice packs on affected areas.
Don't worry, he will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
