In March I did my two treatments. I've been taking Zyrtec to prevent all remaining symptoms and it has worked very well. Since then, I've had very little itching but I have had red lines and marks appearing up and down my arms, particularly when I do any physical labor. In the last couple days I ran out of Zyrtec and I've started experiencing the numbness and bumps that came with scabies... is it possible that I still have the mite or should I just get back on Zyrtec?
