A 32-year-old female asked:

i took famciclovir for 7 days to treat cold sore. i read where i just needed to take a single dose. is this okay? or will this hurt me in some way?

Oral herpes Rx: There has been no research on single dose famciclovir for treatment of oral herpes, but a big enough dose probably would work just fine. It would be harmless. But to be certain, for future outbreaks use the approved and recommended treatment, a single 2 g dose of valacyclovir (Valtrex and generics).

Is it common to have a sore arm after donating blood a month ago?

No: If you donated blood a month ago, you should not be having pain. This would most likely be from phlebitis or irritation to the vein. I would have someone take a look at this or call the facility that drew the blood.

Muscle pain?: Pain in back muscles is more common reason for this complaint than actual kidney pain. But kidney stone possibility cannot be ruled out. Also, could be related to kidney infection esp if you have signs of of UTI e.g. Burning, frequency, or foul odor with urination. A visit to your doc will help differentiate this.

What can a person do to treat or prevent constant heat rash breakout from(i assume) working all day in the unavoidable heat?

May be hard to do...: People try to live and work in conditions that their bodies are able to adapt to, but sometimes that is not possible. A primary care doctor and a dermatologist can help prevent and treat recurrent heat rash (miliaria treatment). Keeping the skin surface intact, healthy, and normal is important. That means not rubbing the skin with rough clothes, or getting industrial chemicals on them.
