What happens when battery fluid leaks onto your skin? Should I be worried as far as my health is concerned?

I removed some old double-A Panasonic batteries from an old device and the fluid leaked onto my skin. I noticed my skin was wet, and after about 20 seconds I smelled a strong ammonia-like scent. My hand started to feel tight and extremely dry so I washed them immediately. However, here I am a few hours later and my hand feels a bit swollen. Not noticeably swollen b/c others can't tell, but it feels swollen to me. Has this happened to any of you? Is this something that I should seek medical attention for? .

Wash with baking soda, it counter acts acids. Unless you have an allergic reaction you should be okay. I' ve gotten battery acid on me several times here on the farm.

You should wash your hands immediately.
Batteries are acidic! Ointments should be applied to the affected area.

you should definantly seek medical help at first go to the doctors and not rush in to the hospital or er.

batteries are filled with acid. So you have burned your hand. If there are no open wounds you are ok. You did the right thing washing it off immediately.

DEPENDING ON HOW LONG THE BATTERY ACID IS IN CONTACT WITH YOUR SKIN . battery acid is still acid and can cause severe burns.. baking soda helps neutralize the effects but i havent seen it affect me in swelling but others may have allergic reaction to it .
if it persists seek medical attention mj

Yes. No need for medical aid. Apply ice or burnol cream.
These alkaline batteries contain limestone & carbon

Battery fluid is either strong acid or alkaline. If you didn't wash the fluid completely away it could cause inflammation of the skin or WCS the skin could be eaten away by the strong acid or caustic. It may be wise for you to consult a physician.
