My stomach has been sensitive lately, with nausea and diarrhea for two days, which stopped after taking medication to harden my stomach. Now I have stomach pain, a cold, runny nose, and coughing. I'm 22, don't smoke, and don't have a fever. Could this be related to travel stress and different foods from different time zones?

I'm a 21-year-old female. My period stopped abruptly three months ago. I'm not pregnant. This month during the time I get my period, I had thick, stringy brown discharge for the entire month. There have been no other symptoms. No pain, no itching, no discomfort. What could this be? What should I do?

I stepped barefoot onto a small piece of burning charcoal, resulting in a blister on the outside side of my left sole. I've treated it with cold water, ice, and a large band aid. The blister is about half an inch by three quarters of an inch and doesn't hurt unless I put weight on it. I'm wondering if I need to see a doctor, what else I should do, and how long I should expect to be unable to wear shoes.

I am 29 years old, weigh 100 kg, and am 174 cm tall. I often notice my resting heart rate to be in the 50s to 60s. My blood test shows potassium and calcium levels at the upper limit of normal. My blood pressure is normal. I am concerned if this is due to high potassium levels or if it is normal. Can fatigue from stress and lack of sleep cause a low resting heart rate?

We are planning to climb the Kazbek mountain in Georgia, which is over 16,000 feet high, and I am concerned about altitude sickness. Are there any proactive measures we can take to decrease the chance of getting sick?
