If you are a doctor, please answer the medical questions based on the patient's description.

### input:
I have a lump larger about the size of a dime on the top back of my head slightly toward right (if one where to put their hair in a pony tail), it s very tender to the touch but does NOT move when I press on it & from what I understand if it were a pilar cyst it would move. I also have had a headache all day (not severe but enough to be annoying). Also have facial numbness, major vision issues past 24 hours (but also have keratoconus). I have significant history of multiple issues as follows that may or may not be pertinent & just want to know if it is something that can wait until I see either my Neuro Doc next week or my Dermatologist the following week for schedule appointments OR if I should take action sooner: I also have had scalp tenderness off & on as well as other strange neurological symptoms (numbness in buttocks that goes down both legs especially after sitting & diminished memory & concentration etc.) ever since I broke my neck roller blading (Genetic Defect: Reverse Curvature of C-Spine at C-4-5 and have had two cervical spine surgeries - first C3-C5 in 2007 then C5-C7 in 2010). Continued to have falls even after second surgery (most of falls occurred while carrying things with my arms). Six months ago w/o having had any falls in previous 90 days woke up one day and couldn t bare to stand or walk more than about five minutes. I have neuropathy in both of my hands plus arm weakness which worsened significantly since and at this point I can barely lift a half gallon due to pain that shoots down into my low back. Was diagnosed with Facet Joint Osteoarthritis in Lumbar Spine and was referred to NeuroSurgeon/Pain Mgmt Specialist to sever nerves that send pain signals to the brain because physical therapy and all other treatment options have failed plus steroid injections have been tried multiple times and each time produced extreme roid rage. NeuroSurgeon/Pain Mgmt Specialist believes I have Failed Back Surgery Syndrome (FBSS) has already done an MRI of my cervical spine as he feels that everything is the result of an issue in that areas and is trying to get to the bottom of ACTUAL cause of symptoms such as Numbness & falling down for what appears to be no reason BEFORE he just treats lumbar symptoms. Also have significant issues with my jaws (both top & bottom jaws out of alignment) and tried wearing customized mouth piece over the past year but was just told by my cosmetic dentistry specialist that he highly suspects Mandibular Condylar breakdown for sure and need to assess the severity to properly treat (& currently awaiting insurance approval for MRI or Cat Scan).

Hi, Regarding the current issue of facial numbness and mild headache, I think it is safe to say that you can wait till your appointment with your neurologist next week, in order to discuss the issue with.  However, if you develop acute deterioration of your symptoms like loss of vision, one-sided body and/or facial paralysis, speech problems you have to visit the nearest emergency room.  Hope I have answered your query. Let me know if I can assist you further. Take care
