Hi

Welcome to just answer

Can you please elaborate your question

Thanks for the information

Well tetramethrin can cause muscle twitching but that is when you accidentaly ingest the posion... Topical exposure of Tetramethrin for a few minutes should not be the cause of muscle wekness and twitching that you are currently experiencing

Topical exposure just causes skin irritation and redness that you deny to have had experienced

No as long as you clearly washed it and prevented further exposure that shouldn't be the cause to your symptoms

For such symptoms to occur there should be history of more prolonged exposure

Anyways I would suggest you see a neurologist for further help in this regard

You may require a Nerve conduction studies to reach to an underlying diagnosis which is surely not the Tetramethrin exposure that you are co relating

Please follow up with your neurologist and get your nerve conduction studies done

Thank you

You are wlecome

Take care
