You can't have a temporary profile for more than 12 months for the same condition. Any temp. profile over 6 months requires referral to a specialist. Here is the quote from AR 40-501:
"7–4. Temporary vs. permanent profiles
a. Permanent profiles. A profile is considered permanent unless a modifier of “T” (temporary) is added as described
in b below. A permanent profile may only be awarded or changed by the authority designated in paragraph 7–6.
(1) If the profile is permanent the profiling officer must assess if the Soldier meets retention standards by chapter 3.
Those Soldiers on active duty who do not meet retention standards must be referred to an MEB as per chapter 3. (See
paras 9–10 and 10–26 for disposition of USAR and ARNG Soldiers not on active duty who do not meet medical
retention standards.)
(2) Those Soldiers (active duty and USAR/ARNG) who meet retention standards but have at least a 3 or 4 PULHES
serial will be referred to a Medical MOS Retention Board (MMRB) in accordance with AR 600–60, unless waived by
the MMRB convening authority.
(3) Permanent profiles may be amended at any time if clinically indicated and will automatically be reviewed at the
time of a Soldier’s periodic health assessment or other medical examination.
(4) The Soldier’s commander may also request a review of a permanent profile in accordance with paragraph 7–12.
b. Temporary profiles. A temporary profile is given if the condition is considered temporary, the correction or
treatment of the condition is medically advisable, and correction usually will result in a higher physical capacity.
Soldiers on active duty and RC Soldiers not on active duty with a temporary profile will be medically evaluated at least
once every 3 months at which time the profile may be extended for a maximum of 6 months from the initial profile
start date by the profiling officer.
(1) Temporary profiles exceeding 6 months duration, for the same medical condition, will be referred to a specialist
(for that medical condition) for management and consideration for one of the following actions:
(a) Continuation of a temporary profile for a maximum of 12 months from the initial profile start date;
(b) Change the temporary profile to a permanent profile;
(c) Determination if the Soldier meets the medical retention standards of Chapter 3 and if not, referral to a MEB.
(2) The profiling officer must review previous profiles before making a decision to extend a temporary profile and
refer the Soldier to a medical specialist for management if the temporary profile has been in effect for 6 month. Any
extension of a temporary profile must be recorded on DA Form 3349, and if renewed, item 10 on the DA Form 3349
must contain the following statement: "This temporary profile is an extension of a temporary profile first issued on
(date)."
(3) Temporary profiles should specify an expiration date. If no date is specified, the profile will automatically expire
at the end of 30 days from issuance of the profile. In no case will Soldiers carry a temporary profile that has been
extended for more than 12 months. If a profile is needed beyond the 12 months, the temporary profile will be changed
to a permanent profile."
I have seen many cases where the doctors either ignore this regulation or try to get around it by letting the temporary profile expire and then re-initiating it and treating as the first profile.
Only your doctors or other providers can give you any guidance on how to address your medical problems. Though, if you are not happy with the treatment you are getting, you may well want to consider getting a second opinion. As far as outcomes from the administrative side, well, you will either get referred to an MEB/PEB or return to duty without referral. If you get referred to the MEB/PEB, it will follow the course outlined in the regulations (you can find many posts on this, start with the Overview of MEB/PEB process thread). You will either be found fit or unfit (and given appropriate disability benefits).
Hope all goes well for you.
