Regarding tinnitus. Strokes and all.

I have a history of tinnitus from last 4-5 months. I am on aboslut 3g but due to rashes on arms i have stopped it. Tinnitus is now reduced its like a hmmmm sound when i stay in silent place and hissing sometimes when i wake up, its in my left ear. But day before yesterday it felt like my right side head was getting heavy/compressed near right side ear while i was lying down and a tinnitus wave in right side started at 9khz frequency (i matched it with an online frequency maker). It was very weird and it lasted for 10-15 sec and went away. I very much scared abt what if this tinnitus starts in both the ears or of something wrong is in my head due to which dis is occurring at first.. this compression incident occurred to me before too but not in this intensity that happened yesterday. Please help me and what I should do during this lockdown to ensure m alright :(. I am very much scared about strokes and all.
