My legs, calves and feet are constantly itching red a bit swollen and burning and I ve used anti itch and benidryl spray but that provides only temporary relief. Showering helps but as soon as the skin is dry it starts to itch and I have had some hand and upper arm itching but mostly the lower extremities. There are no major blisters or areas that show up spots but it seems like it is under the skin and only gets worse with itching It has gotten worse lately and am wondering if the mosquito bites that I occasionally get seem to set off an attack are the initiators and create a reaction. I do not know how or what to use to prevent the itching. Wakes me up at night or starts when just sitting still.
