Question: Good evening,

3 months ago I suffered a sever concussion and had symptoms until about 3 weeks ago. I believe as part of my injury I experienced whiplash. Two weeks ago, when trying to return to the fitness center I injured my neck which resulted in me having facial numbness for a couple of days as well as finger numbness and twitching. I took some naproxen and the symptoms got better after a few days, however since a week ago I've been feeling as if there was some cold liquid on top of my head. This feeling comes and go and I've noticed my arms go numb when I sleep and sometimes it takes me about 20 second to get them back to normal. I am quite nervous if this can be due to the neck injury or if it is a sign of something more serious such as a neurological disorder.

Brief Answer:
Nothing serious.

Detailed Answer:
I read your question carefully and I understand your concern.

The combination of the cold liquid feeling with arms going numb during sleep is not indicative of a neurological disorder. That is because those symptoms do not correspond to a common brain or spinal cord region, could not be due to the same lesion explaining them. The fact that the symptoms fluctuate and aren't permanent supports that as well.
What could be the reasons....regarding that cold feeling I believe that unless there are any dermatological issues, any visible scalp skin changes, it is more likely due to anxiety. It is not due to a neurological issue, not only doesn't correspond to a brain area as I said but neither to any peripheral nerve distribution.

As for the arms going numb during the night that could be due to peripheral nerve compression. It may happen due to compression in the neck, or more downwards such as the thoracic outlet or carpal tunnel syndrome. The recent neck issues you've had would make the neck the most likely culprit. For the moment I would give it some more time. If symptoms persist then perhaps a neck MRI and nerve conduction studies might be considered.

I remain at your disposal for other questions.

Hi, I underwent carpal tunnel surgery last year in Aug. The tingling and numbness in the fingers went away after the surgery. However post surgery my hand used to swell a lot and it too till dec to even be able to open the hand out completely. Most of the other symptoms have not gone. the below are the symtoms i still have cold forearms and upper palm Burning and excrutiating pain radiates up the center of the forearm and into the shoulder Overall decreasing grip strength in the hand - around 2kgs only when working on the computer the hand hurts a lot, the part of the lower forehand hurts very very much, leaving me stopping and massaging the hand, hand goes limp and very weak Extremely Weak hands and limited ability to cut vegetables, brush my teeth, comb my hair, carry a full cup of tea. Finger pain, finger numbness and/or finger clumsiness particularly in the thumb and/or in the index or middle fingers. Constant aching of the upper shoulder and neck. The doctors say it is complex regional pain syndrome however I feel there is something that has not been investigated but I do not know what to do and who to ask

I have several neurological symptoms and would like to know if there is a connection. I am a 58 yr old female. A lot of the symptoms started in my 20's; most are progressing at a markedly increased rate in the past few years, and affecting my work and life in general, to include:
- Finger numbness/pain, since age 20 - worse in cold weather, wakes me up at night, makes typing, writing and carrying objects difficult; started dropping dishes lately.
- Numbness/pain in feet, since age 30 - much worse now, cannot walk without shoes.
- Right hip/leg giving way without warning, since age 56 - I stumble and/or fall. Some pain associated at top of leg.
- Headaches, since age 12.
- Migraines, since age 28 - several a month; can last hours to days; almost always starts in left temple.
- Knee pain, since age 12 - severe pain when climbing/descending steps. Arthroscopic surgery on both knees in
20's and 30's. Can no longer play sports.
- Tremor in right hand, since age 28; diagnosed as essential tremor - has progressed to both hands; more
pronounced with movement, but has recently occurred during rest.
- Head/neck tremor, since age 57 - recent onset.
- Tourettes Syndrome, since age 9. Facial ticks and throat clearing. Not as pronounced since age 40.
- Loss of balance and falling, since age 40 - much worse now at age 58.
- Memory loss/fog, since age 55 - symptoms increasing.
- Fatigue, since age 35 - symptoms increasing. Some days can hardly move for hours.
- Depression, since age 35 - symptoms steady until age 55; decreasing.
- Concussions with and without loss of consciousness, due to falls.
- Leg cramps/charlie horse in calf and arch of feet, since age 12 - right and left.
- 6 miscarriages, 3 live births, ages 24-31 - severe toxemia and per-eclampsia with all three pregnancies/births.
- Sleep apnea, since age 50.
- High blood pressure, since pregnancies.
I have moved a lot across the US and overseas with my ob and it seems every new doctor with each move wants to start testing all over again (they won't use the results from another state/country) and I never get a definitive or continued diagnosis. I have been diagnosed with Lupus, Essential Tremor and most recently Parkinson's Disease. But then when I move, sometimes the new internal med or neurologist will disagree with a previous diagnosis. I am frustrated that the symptoms are increasing and want to know what is wrong.
