Spots on my arm - maybe keratosis? Please help!

[CWKR]

Hello. At the beginning of the year I spent a couple of months in Thailand. After a while I noticed a few spots on my forearm, since then they have multiplied and it is getting worse, before they had no feeling but in the last few days they have become really red and itchy. From searching online I'm thinking that it could possibly be keratosis?

Anyone have any idea what this is?

I'm sorry I don't know much about keratosis but you should probably get your on-line diagnosis confirmed or otherwise by your GP!
