Not exactly a topical product but I love this ice roller as a massage tool for my jaw, face, and neck! Something you could use while studying too :) I've had a lot of success with it in the past few weeks, using it about once a day mainly on the side that is causing me the most pain (and its good for your skin too so win win!) https://smile.amazon.com/gp/product/B01FDKX3MS/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
