I'm wondering if it's okay for someone with typhoid, or someone who's just getting over it, to stay in an air-conditioned room. Is it safe or should it be avoided? Any advice would be appreciated.

Yes, it is safe for a typhoid patient, or someone recovering from typhoid, to sit in an air-conditioned room. It is important to maintain a comfortable temperature for the patient. Additionally, staying in a cool environment can help reduce fever and promote overall comfort during recovery.

I've been feeling a weird pain in the bone area near my chest, just to the left of the breastbone. It really hurts when I press on it, and sometimes I get this sudden shock-like pain when I breathe. When I don't press it, there's usually no pain. What could be causing this?

I've just gotten over typhoid and I'm out of the hospital now, but I'm still feeling super weak, especially from my chest down to my stomach. It's a really noticeable kind of weakness. Can you help me understand why this might be happening?

It's common to feel weakness after recovering from typhoid, especially in the chest and stomach area, as your body is still healing. The infection and treatment can take a toll on your energy levels, and it may take some time for your strength to fully return. Rest, proper nutrition, and hydration will help support your recovery.
