This girl kicked my hand or wrist area a month ago. My elbow was sore for three to four days, and ever since, I would wake up with a sore elbow, which would calm down in half an hour or so. It was not swollen, but the pain came from the inside and was really sensitive when I would tense my muscles. Today the pain lasted for the whole day. Could there be something wrong, considering it has been a month since the injury? I do Taekwondo so my muscles in my arm are quiet stable.
