Hey Netty, as your history is quiet vague we will not be able to help you out much in this case... A good history and assessment is very important for a physio to better understand what to do next.
Anyway, the humps & lumps that you are talking about are very normal and not necessary related to shin splint... I am sure if you palpate your own shin you would find them.
Was the patient dormant for a while and then started running all at once? OR is there any change in his running norms, like did he change his shoes? or place in which he ran? or intenstity of it?
