Tight temples?

I’ve been very stressed out lately due to some health issues I have and it’s been so bad that my neck and shoulder were hurting for like 2 weeks straight. Well a couple of days ago I noticed my jaw started hurting specially when I yell or talk loud and now it’s my temples they feel so tight 😥 I’ve been clenching my jaw a lot while sleeping lately so I know that’s the cause of my temples and jaw hurting. As much as I try to relax them I find myself later tensing them up again. They hurt so much 🙁 I can’t even make any facial expressions from how bad it is. Can anyone relate or have an Tips on how I can relieve this stress and anxiety naturally without medication?
