Scalloped Tongue. From the tongue issue.

I am having teeth impression on my tongue for last 40 days. Also I have sensation as if my tongue is burnt with some hot food. No pain I got preventive health checkup done in Feb'21 and I came to know that my thyroid was at the higher end TSH 6.6 also serum uric acid was slightly higher 7.4. Doctor advised me for thyronorm 25 mcg for 6 months and omega 3 capsules for 2 months and to again get thyroid profile done after 6 months. For last 6 months I was under extreme stress for the treatment of my father's tongue cancer and for 2/3 months my diet was also improper. Is the problem I am facing because of the 3 reasons I mentioned 1. Thyroid 2. Stress 3. Improper Nutrition Please advise what should I do to get relieved from the tongue issue.
