Visceral Vs Parietal Pain
Multiple pathologies: Inflammation of the pleura, pleurisy, may be due to infections in the pleural cavity or overlying lung. There is generally inflammation of the pleura overlying lung infarcts.

how can pleura thickening cause pain if it originates on the visceral layer which isn't sensitive to pain?
Pleural innervation: It's true that the visceral layer of pleura has no sensory innervation. But the other layer of pleura -- the parietal pleura -- is continuous with the visceral one and lines the inside of the chest. This parietal pleura is richly innervated via intercostal and phrenic nerves, and is very painful when injured or inflamed. Ask anyone who's been awake while receiving a chest tube. ...Read moreSee 1 more doctor answer

Dear doctor, why doesn't pleural plaques cause chest pain if they originate in the parietal layer?
Pleural plaques: Are fibrous tissues once seen and not inflammatory processes that can cause stickiness of the pleural surfaces. Like most scars that we have, the nerves in that area is either destroyed or not exposed, (try to touch your scar). And hence there is no pain. There are those who do feel persistent pain. ...Read more

The jaw hinge joint, or TMJ, is very susceptible to stress and effects from muscle tension. I suspect the muscle overlying the scalp area you describe is being affected.

Have throbbing pain in left parietal lobe. Began less than 24 hours ago but will not go away. Stops for short time then starts again. Brain tumor?
A wee clarification: 1) You cannot have a pain in your left parietal lobe. Your brain has no pain nerves. All sensations are processed in the brain but experienced elsewhere in the body. 2) The brain has no connective tissue. Lots of connective tissue around the brain, however: Meninges, arterial sheaths, other connective tissue, all of which is exquisitely sensitive to pain. That's what pains and throbs. ...Read moreSee 1 more doctor answer
