Can you get muscle pain from being hit by a pitcher?

Many of you must be having a hard time due to pain when receiving treatment at dermatology or dental clinics.
I also tend to react sensitively to pain, so there are often times when I endure the pain even though I want to get a procedure.
There are years when I skip getting the flu shot because the pain is so severe for me.
So, are there any of you who have suffered from pain while struggling with the mound?
If I get hit by a mound and feel pain, should I stop?
Just when one worry ends, another one comes up, so when will I ever be able to finish my diet? Haha
