Hi! Good morning. I am Dr Shareef answering your query. I would agree with your doctor that it could be infection of the hair follicles due to picking at them resulting in several of the infected bumps/sores in your scalp. The lymph nodes swelling on your neck might be due to the spread of the infection to the draining nodes. The nodes would remain there till the sores were treated appropriately by antibiotics and anti inflammatory along with proton pump inhibitor drug. If I were your doctor, I would advise you not to prick the already infected sores, wash them with some anti septic solution, go for some broad spectrum antibiotic along with anti inflammatory with a proton pump inhibitor drug. This would help your sores heal. If not, then you might have to consult a general surgeon for a possible histopathology of the sores. At the same time, a routine check up of your blood sugar might be helpful. The sleep disorder you mentioned might not be related to the sores on your head. You might have to get yourself reassessed by your treating doctor/psychiatrist for this part of your problem. However, I could suggest you for regular routine aerobic exercises which would do over all good to you. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
