I was diagnosed with cellulitis bad circulation in my legs is there some kind of treatment for this?

Yes: Cellulitis is treated with antibiotics, and when severe may require iv/im route. Bad circulation may be arterial (at age 48y, may be early, but possible with strong family history, diabetes). Venous incompetence may be the problem, with associated lipodermatosclerosis resembling cellulitis being present. See www.Phlebology.Org and find phlebologist in your area who can help you.

Yes for both: Cellulitis is skin infection and is treated with antibiotics-- typically you need to have an adequate blood supply in order for the antibiotics to reach the site of infection though. If your blood supply is poor, you would need further studies to identify why and where exactly the problem is, such as angiogram, ct or mri, and then there are many options to improve it with stents, bypass etc

Compression/eval: You may need detailed evaluation of your veins to rule out venous insufficiency. Regardless, mild to moderate compression stoclkings will likely benefit you.
