I went to the er a couple months ago because of pains in my arms by my arm pits and my legs on the inside up by my groin. This Week I went to the dr because of a lump in my neck now I have another on the same side and another on the opposite side in the same spot. Should I be worried?

Should you be cautious yes. Has your doctor discussed what is going on? You might even look into changing your diet to help with the healing. What you have would give me a high amount of concern and lead to doctor visits to get through it.

The lumps you feel are lymph nodes. An early warning of infection in the body, yes, you should be concerned.

As tickle says, and you should not go to an ER but to a clinic, either walk in or by appt, for proper non emergency care. It's urgent, but ERs these days can really only handle true emergencies. Many hospitals have a walk in affiliate.
