Q. I have constant pain on my feet more on my bones than anything,do I have arthritis? I do already have plantar fascictis

A. Chronic arthritis is a disease of the elderly and it isn't common to suffer from it in young age, however joint pain or bone pain can be caused by several other reasons, that might not be chronic, such as an infection, excessive physical activity or such. You should see a doctor to evaluate the pain and joint movement. He/ she might send you to do an x-ray to see if there's something they can see that is wrong with the joint or bone (dislocation or fracture).

Q. Is it normal for someone with untreated Adult ADHD to have constant, worried thoughts? As a child I was diagnosed with "off the charts" ADHD and took medication which fixed the problem for about 7 years. I ended the medication in junior high and now I am in college. I am no having constant worried thoughts and my mind is always racing. I think this may be the ADHD back now as an adult, would this make sense?

A. Attention Def is often goes hand in hand with Depression. Depression is often missed in diagnosis because the person suggests that they are not sad and don't cry often. Depression might better be described as a feeling of emotional heavyness or pressure without a real reason. This feeling of emotional heavyness is awful and people will try to find reasons to explain why they feel this way so that they can do something about it. Generally, if a person makes a decision about something, such as paying a bill, this heavyness will lift for a while and the person can move on to another thought. When a person is depressed this heavyness is lifted but only for a very short period of time, sometimes only for a few seconds, and the person cannot move on to a new thought. Instead, the tendency is to rethink the same thought over and over to get, although short lived, a bit of emotional releif.
