I Broke My Calcaneus And Lisfranc About 2.5 Months Ago.

I broke my Calcaneus and Lisfranc about 2.5 months ago. I had surgery as have been nwb. Next Wednesday I have my doctors appointment to be cleared as pwb. My shin as of two days ago has started throbbing and unless I’m laying down I can barely stand the pain just sitting in a chair is almost too much to bare. There’s no bruising or swelling just unbarable pain. What’s wrong with it? Should I go to the hospital?
