Husband needs a CT scan

So just want some peace of mind...

My husband has had a bad headache for 3 weeks now. It started off very severe to the point where he went to the ER twice. He got antibiotics and also developed shingles in the process of all of this 🤦🏼‍♀️

Covid test was negative but he still has slight pressure in his head and feels “off” so his doctor ordered a CT.

We are both freaking out awaiting results. Has anyone had something similar happen to them and it turned out not to be anything serious? My mind just thinks the worst unfortunately and we have such anxiety about it. Any advice is greatly appreciated. ❤️
