I don't know why, but I have these itchy bite/bumps on my upper arms. I dont know where they came from. They are only on my upper arms. This weekend I was around mosquito's, but I don't know. Are bed bug bites just like mosquito bites? I doubt I have bed bugs so Im just confused.
Bedbug bites resemble mosquito bites in that they do itch and produce a swollen bump on the skin. If you want to determine if you have bedbugs try checking the seams in your mattress. You need to also check the cushions of your couch and its seams as well. Identifying bedbugs isn't that difficult. Try looking for an insect that is about 1/4th of an inch long and has a flattened red body. Most likely you have been bitten by mosquitos.

It sounds like mosquito bites. Bed bugs would bite you on your body, not just your upper arms. But your uppser arms were probably exposed to the air, and are better targets for mosquitos than your lower arms which move around a lot more.
Bed bug bites can indeed look like mosquitoe bites. My boys had a bought with them not long back. Those little critters are extremely hard to get rid of. We wound up throwing out everything, beds, furniture and all just to get rid of them. Google bed bugs so that you can get infomation on what to look for. Good luck to you.
