Hi! I fell approx 6 weeks ago and received a concussion. I still have a very sore, painful lump on my forehead and many other symptoms, but about a week ago or so, I developed an itchy raised rash on first one arm, then other arm, then on the front of one leg and now a little on my chest. I went to the E.R. Two times now, but that was for a headache so bad I thought I would die. My neck was sprained also. And for a little less serious headache and confusion and just feeling so horrible. And both of those visits were within a week and a half of the fall. Please help. I don t have a dr at this time.

Hi! Good evening. I am Chat Doctor answering your query. The symptoms on your body and the headache along with the painful lump might not be related. The painful lump could be a hematoma of the scalp which possibly getting inflamed causing the pain. The hematoma not subsiding for last 6 weeks needs to be investigated. I am not aware if you are on any kind of blood thinning agent or not, and if so, you might have to consider stopping it on consultation with your family physician. If not, then I would advise you for a CENT scan of the skull to rule out any intracranial communication of the hematoma. Further management of this lump would depend on the report of the CENT. The rashes on your body could be due to some kind of allergy (to any medications which you might have consumed in between) or due to some and of skin infection. This could be diagnosed only on physical examination and clinical assessment, and so I would suggest you to consult a dermatologist in your area for this symptom of yours. Till then, you could go for an anti histamine Chat Doctor. 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 Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor.
