Whenever i inhale, i sometime feel sudden little clenching tightness at back of head which comes and goes, sometimes it doesn't even happen, If i close my eyes and lie down i feel like inside head clenching at back but it eventually settles down after i remain in one position for sometime however it disturbs my sleep quite a lot because i feel odd motory sensations. I also noticed when i close my one ear which have little swelling since two days, the feeling is not noticeable much, no pain or fever whatsoever.
