The lesions on your legs & the callouses on your hand may not be related.
How long exactly is a few months that the itching began? Did you see any doc hitherto & was there any creams et al applied? Does anyone in your vicinity or family or the friends circle have something similar? Does the itch get worse or get better at any points in the day?
Dermatology is a visual line & as such, one would prefer a clear digital image of the lesions & you may upload it on this site using the upload data icon situated to the right of your screen.
In the meantime, do apply a calamine
lotion to the leg lesions & a n ointment containig betamethasone
& salicylic acid
on the palmar lesion. This should provide you relief. Howeverm it may require a skin biopsy
from the leg lesions to confirm a diagnosis.
Good luck & Godspeed & hope you have a clear skin soon!
