Occasional Tinnitus. I panic alot.

I experience occasional tinnitus with a frequency of less that once per month with ear fullness which lasts for a 5 to 10 seconds. Once after catching cold I had tinnitus for a week which was around 6 months back which was not troublesome after taking some cold medicines it went away. Both the types of tinnitus tones i hear is different . My hearing is proper but I get anxious and stressed very soon. And I have low BP 90/60 most of the times and observed i get ear fullness under stress or sleeplessness or low BP or indigestion or no when there is no physical activity . Should I be concerned or this is normal to experience. I get stressed easily and even thought this does not last longer i panic alot.
