I'm sorry to hear you are feeling these symptoms again after so long.
Side effects are reported after the Covid vaccines, and parasthesia is one of them - usually affecting the injected arm, but also other areas more rarely. However, the usual onset is within 7 days of receiving the vaccine, and nearly all symptoms disappear within 30 days.
Since it took a very long time for you symptoms to appear after the injection, you should consider consulting with your PCP or neurologist.
While we hear about Covid vaccine side effects everywhere, everyday, it is possible that it could be a coincidence and not a reaction to the injection.
