I too have this. Stings like hell. I’ve dropped my phone, from a sitting position. I also limit driving, as my legs jerk when stung. I have a really strong batch.
It may be due to the fact I was given steroids, minimal anti parasitics, and then an immunosuppressive drug. I totally got screwed.
I’ve tried the shop with medicines, doctors. If you’re early, Albenza may do the trick. Eat garlic cloves, bone broth. If doctors wait too long, it’s a real nightmare.
