Hi, and welcome to the MS forum. I see that you posted this also on the Neurology Forum.
You said you have an appointment with your regular doctor on May 4th. Have you seen any other specialist regarding your symptoms?
Some of your symptoms do sound neurological but as you know we cannot diagnose you over the internet. What we do have to offer is support and information. If you haven't already noticed our Health Pages, they can be found on this page at the upper right corner of the page, next to the yellow icon. these pages contain a wealth of information.
One of these Health Pages deals with muscle and spasticity. You might find some answers in this pages. Here is the link to that specific page:

Before you go the May 4th appointment you might want to look at the Health Page concerning making a timeline of your symptoms and what helps your pain and what makes it worse.
We are here to provide support and information so let us know hoe things go.
One word about posting. Many of us on the boards have vision difficulties so in the future it would be helpful if you broke up your posts into smaller paragraphs ,as I have done here. It's easier to read and may result in more responses if others can read it.
Wishing you luck and relief from your pain.
