What drugs are you taking? I have similar sensations and am taking sorafenib. I have been told I can take 2 x 25 mg of benadryl every 4 hrs to reduce this. If it gets to your face you can use benadryl cream or steroid creams. Also, a mild-drandruff shampoo may help your saclp.
Good luck.
If all this fails then a dose reduction may be an option.
