Sometimes I get a headache which appears on different spots of my head, moves from one spot to another, disappears and comes again. The tongue issue worries me a lot.

Sensation of numbness of the tip of my tongue since 3 weeks ago. What does it mean?

I'm very sorry but you won't get a diagnosis online, it's not possible.

Numbness can be caused by many different things, some easily diagnosed and treated, others not.

You need to see a doctor about this issue. No one online can help you.

Good luck.
