My dog has a scabbed up rash in his arm pit in groin area. He won't quit licking it, and it seems to be getting worse. They look like tons of bug bites but I'm not sure

Ok. The first thing you need to do is stop him from licking!! You can go to any large pet store and purchase an Elizabethan collar (aka: E-collar, cone). Take him with you when you buy it as it needs to be properly fitted. The cone portion must be long enough to go past the end of his nose or he will still be able to lick. https://www.youtube.com/watch?v=-x64MQlDPeo It will never get better if he doesn't stop licking it. Second step is to use a topical medicated shampoo and spray like the ones I linked to below to see if you can get the rash to clear up. If the rash does not start to look better within 5-7 days then you will need to get him to your vet for an exam. First bathe with the shampoo. Follow the instructions to a "T" on the label. After he is dry you can use the spray as a leave-on treatment. Spray 2x a day. Bathe him every 3-4 days during the treatment period but use the spray every day. https://www.chewy.com/douxo-chlorhexidine-ps-shampoo-dogs/dp/110818 https://www.chewy.com/douxo-chlorhexidine-micro-emulsion/dp/111700 Hope this helps.
