Welcome to just answer

Dr Wajid :

Can you please elaborate your question

Customer: Was wondering how
Customer: Was wondering how long it takes for chemical
Customer: Poisoning to take effect. I had got flea spray on my legs. I washed it off within a few minutes. It contained tetra
Customer: Tetramethrin.
Customer: A week later I started gettin weak legs and muscle twitching.
Customer: It seems to happen mainly in the evenings. Over this last week it has moved into my arms as well
Customer: It said that chemical can cause skin irritation and redness but that never developed.
Dr Wajid :

Thanks for the information

Dr Wajid :

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

Dr Wajid :

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

Customer: I wasn't sure since I didn't develop the skin irritation or redness. Wasn't sure if it could still be absorbed into skin without the redness showing up
Dr Wajid :

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

Dr Wajid :

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

Dr Wajid :

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

Customer: It was just that one day where it happened. It was over a week before the weakness and twitching began.
Dr Wajid :

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

Dr Wajid :

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

Dr Wajid :

Thank you

Customer: Okay thank you for the answers and advice.
Dr Wajid :

You are wlecome

Dr Wajid :

Take care
