Can plantar fascitis cause severe pain in the middle of the night? i was diagnosed a few days ago but suspect more may be going on.

Yes - but be hopeful: Here's a link to start with. Humans can have multiple issue.as well as varying responses to everything. This is not unexpected. Read this, try the first steps and keep going until you do as much as you can reasonably do. Work w/ your providers realistically. It's always the best plan. https://www.painscience.com/tutorials/plantar-fasciitis.php. Best wishes!
