If One Claim In, Can I File Another Supportive One?

[autumn]

PVA has my claim now working on getting the MS secondary issues lined out.

i have medical documentation that supports SC for another part of my spine that was injured while active duty. PVA said they don't want to file that yet and to wait until all this MS stuff is done.

would it be unwise to file the other claim myself? at the least to get the supportive data into my c-file? the VA raters are very busy as is the VA. my way of thinking, and it certainly could be wrong hence i ask you folks, is to get the supportive claim in.

i have some significant spinal degeneration issues and want to file for an increase in my SC for it. i have another pending claim in and don't want to delay/jeopardize it but i've read one should file as soon as possible some claims so the effective date isn't lost.

what to do?
