A serious issue I do have. I have air gasping problem in sleeping. I thus can't sleep. During sleeping, I feel as if my brain is a battery. When sleeping it is literally like charging, and when I am going to doze off, I feel depersonalisation. All day, I have vertigo and giddiness in brain. I am pretty sure that the brain in not properly supplying the Oxygen in my body parts and therefore feeling gasping(in exhale time only). एस्तो अवास्था मा ब्रेन टूमोर वा अन्य बडी टूमोर को संका गर्न मिल्छ? This seems not anxiety disorder/panic attack. I feel somethin' wrong in brain & circulatory parts so I am having severe sleep problem. Head feels tinnitus (buzzing sound) also. I am 35 years old male. I haven't gone through any serious medical investigation before neither I have had a single pills of any particular disease. please suggest.
