Im sorry to hear about your condition. There are number of things which can cause these sort of enlarged lymph nodes. Some of them are benign while others can be more serious in nature. Now the cause of these lymph nodes can be determined only after a complete clinical examination, the reason for this is that many of the causes can only be picked up after determining the consistency and size of the lymph nodes.
Now in your case, as you have not mentioned any other symptoms, its likely that this can be due to a localized infection. Yopu have mentioned a couple of acne spots, these spots can also be the start of a rash. A picture would be helpful in narrowing the diagnosis. Simple infections of the lymph nodes can cause them to be inflammed and painful to touch. The area overlying them can be red in color. Now in most cases simple antibiotics can help in reducing the inflammation and getting rid of the infection. the infection can be present in the region which is drained by the lymph nodes which in this case can be the arm and hand and the chest wall.
Now apart from an infection this can be due to other conditions such as a malig***** *****ke lymphomas which would present with enlarged lymph nodes which are firm to hard in consistency, or even rubbery in nature. Usually these are painless in nature. This can be diagnosed with the help of a lymph node biopsy.
Now i would recommend taht you get a clinical examination as soon as possible and if needed get a lymph node biopsy done. As this will be the only way to diagnose the underlying cause. If you have anymore questions, please feel free to ask them.
