My right index finger is red swollen hot and the pain is unbearable.
Could be an infection. If the redness and swelling start to spread down into your hand, get to the ER immediately.
Did you hit it really hard on something? If you, maybe you popped a blood vessel. That happened to me once, and I could barely move my finger for a week. Or you could have sprained or broken it. You should see a doctor about it.
Do you need a tissue?
Are you allergic to anything?If so, you may have had an allergic reaction.. :LHope it gets better soon! <3
A dr must see it.It can be infected.
