I'm a doctor myself. And I'm confused what the guy is suffering from.
Asking for Preferences
He's a 15-year-old boy, and he has radiating pain in his right arm, and sometimes he feels his arm is heavy. But on MRI of spine, cervical lordosis has little lost. That's it. Uh, and then his lumbar L3-L4 has disc bulge, but not prolapse and not herniation. It's just, uh- Mm-hmm ... simple disc bulge. So as a physiotherapist, um, it is difficult to diagnose what he's suffering from because he also has symptoms such as dizziness, but there is no cervical, um, pathology or any disc bulge or any herniation or something. Yesterday, he got a little dizzy and... I will share you his... Blood reports, which I told him to go for a test.

This is his report. I'm Dr. Rupak. And I'm his Physio.

I have all the data I need. Let me now analyze this carefully alongside the clinical picture.
Here is a full breakdown for you, Dr. Rupak:
Lab Results - Tejas Gangurde (15 yr, Male) | Dated: 09-07-2026
CBC Findings
| Parameter | Result | Reference | Status |
|---|---|---|---|
| Hemoglobin | 7.9 g/dL | 13.5 - 17.5 | LOW |
| TLC | 11,300 /cumm | 4000 - 11000 | Slightly HIGH |
| RBC | 5.99 million/µL | 3.8 - 4.8 | HIGH |
| PCV (Hematocrit) | 23.7% | 36 - 46% | LOW |
| MCV | 39.6 fL | 83 - 101 fL | Severely LOW (Microcytic) |
| MCH | 13.2 pg | 27 - 32 | LOW |
| MCHC | 33.3 g/dL | 31.5 - 34.5 | Normal |
| RDW-CV | 21.2% | 11.6 - 14 | HIGH |
| Platelets | 4.94 lakh/cumm | 1.5 - 4.5 lakh | Slightly HIGH |
CRP
| Parameter | Result | Reference |
|---|---|---|
| CRP | 81 mg/L | < 5 mg/L (typically) |
CRP is significantly elevated - strongly positive for active inflammation.
Clinical Interpretation
1. The Anemia Pattern - This is KEY
The CBC pattern is classic for Thalassemia (Beta-Thalassemia trait or intermedia):
- Very low MCV (39.6 fL) - severely microcytic
- Low Hb (7.9 g/dL) despite HIGH RBC count (5.99 million)
- Low PCV + High RDW
- Elevated platelets (reactive)
In iron deficiency anemia, RBC count is usually low. Here, RBC is high with low MCV - this is the hallmark of thalassemia, not simple iron deficiency.
This anemia alone explains:
- His arm heaviness (muscle hypoxia from low Hb)
- Dizziness (cerebral hypoperfusion from low Hb)
- Fatigue-like heaviness in the limb
2. The Elevated CRP (81 mg/L)
This is significantly elevated and indicates active systemic inflammation. In a 15-year-old with:
- Dizziness
- Radiating arm pain
- Elevated CRP
You need to rule out:
- Rheumatic fever / Rheumatic disease (especially given his age)
- Juvenile Idiopathic Arthritis (JIA)
- An active infectious/inflammatory process affecting the cervical region or brachial plexus
3. The Arm Symptoms (Radiating Pain + Heaviness)
The cervical lordosis straightening is likely postural/muscle spasm-driven, not a primary structural lesion. With Hb of 7.9, muscles are chronically underoxygenated. Combined with elevated CRP suggesting an inflammatory process, the most likely cause of the radiating arm pain is:
- Cervicogenic referred pain from paraspinal muscle inflammation (driven by the elevated CRP)
- Possibly thoracic outlet or brachial plexus irritation (needs clinical exam - Adson's, ULTT)
- The L3-L4 bulge at age 15 is incidental
What I Would Recommend, Dr. Rupak
-
Refer to a hematologist urgently - get a Peripheral Blood Smear + HbA2 electrophoresis (HPLC) to confirm thalassemia trait vs. intermedia. HbA2 > 3.5% confirms beta-thalassemia trait.
-
Investigate the CRP - get ESR, ASO titre, anti-CCP, ANA to rule out rheumatic/inflammatory cause. This elevated CRP is what could be driving his radiating pain.
-
As physiotherapist - hold aggressive cervical traction or manipulation until the inflammatory picture is clarified. Gentle cervical stabilization exercises are safe; traction over active inflammation may worsen symptoms.
-
Dizziness in context of Hb 7.9 is largely explained by anemia - treating the underlying cause should resolve this.
The combination of thalassemic anemia + elevated CRP in a 15-year-old is a picture that needs physician co-management before physiotherapy can be optimally directed.
It's not 81. It's 8.1
Good catch, Dr. Rupak. That changes things meaningfully.
CRP of 8.1 mg/L is only mildly elevated (normal < 5 mg/L). This is a low-grade elevation, not the picture of active systemic inflammation like rheumatic fever or JIA. It could reflect:
- Minor muscle strain / postural stress
- Mild viral illness
- Or simply the physical stress on his body from chronic anemia
Revised Clinical Picture
With CRP at 8.1, the inflammatory hypothesis takes a back seat. The dominant finding is now clearly:
Severe Microcytic Anemia - Likely Thalassemia
The CBC pattern remains unchanged and is the most important finding:
| Key Finding | Value | Significance |
|---|---|---|
| Hb | 7.9 g/dL | Severe anemia |
| MCV | 39.6 fL | Severely microcytic |
| RBC | 5.99 million/µL | HIGH despite low Hb |
| RDW | 21.2% | High - anisocytosis |
High RBC + very low MCV + low Hb = classic thalassemia pattern, not iron deficiency (where RBC would also be low).
What This Means Clinically
His dizziness, arm heaviness, and reduced endurance are almost entirely explained by Hb of 7.9. At this level, muscles and brain are chronically under-oxygenated. The "radiating pain" with heaviness in the arm is likely muscle fatigue and hypoxic pain rather than a true radiculopathy.
The cervical lordosis reduction is most likely postural / muscle guarding, exacerbated by chronic fatigue from anemia.
Recommendations for You, Dr. Rupak
-
Refer to physician/hematologist for HPLC (HbA2 electrophoresis) - this will confirm beta-thalassemia trait vs. intermedia. This is the priority.
-
As physio - don't chase the MRI findings aggressively. The structural changes are likely secondary. Once anemia is addressed, re-evaluate how much of his arm and neck symptoms persist.
-
Neurological screen - if arm symptoms persist after anemia correction, then revisit with a proper neurological exam (ULTT, Adson's, Spurling's) to look for thoracic outlet or brachial plexus involvement.
-
The mild CRP of 8.1 does not suggest active inflammatory disease - no urgent rheumatology workup needed at this point.
